R th j-amb2If the power dissipating pins(the four central ones),as well as the others,have a minimum thermal connection with the external world (very thin strips only)so that the dissipation takes place through still air and through the PCB itself.It is the same situation of point above,without any heatsinking surface created on purpose on the board.Additional data for the PowerDip package can be found in:Application Note9030:Thermal Characteristics of the PowerDip20,24Packages Soldered on1,2,3oz.Copper PCBTHERMAL DATASymbol Parameter DIP20SO20Unit R th j-pin Thermal Resistance,Junction to Pin1217°C/W R th j-amb1Thermal Resistance,Junction to Ambient(see ThermalCharacteristics)4065°C/WR th j-amb2Thermal Resistance,Junction to Ambient(see ThermalCharacteristics)5080°C/W Figure1:Printed HeatsinkL63744/13OVERTEMPERATURE PROTECTION(OVT)If the chip temperature exceeds T h(measured in a central position in the chip)the chip deactivates itself.The following actions are taken:-all the output stages are forced in the”three state”condition,i.e.are disconnected from the output pins;only the clamping diodes at the outputs remain active;-the signal Diag is activated(active low). Normal operation is resumed as soon as(typically after some seconds)the chip temperature moni-tored goes back below T h-H T.The different upper and lower thresholds with hysteretic behavior,assure that no intermittent conditions can be generated.UNDERVOLTAGE PROTECTION(UV)The supply voltage is expected to range from11V to35V,even if its reference value is considered to be24V.In this range the L6374operates correctly.Below10.8V the overall system has to be consid-ered not reliable.Consequently the supply voltage is monitored continuously and a signal,called UV,is internally generated and used.The signal is”on”as long as the supply voltage does not reach the upper internal threshold of the V s comparator(called V sh).The UV signal disap-pears above V sh.Once the UV signal has been removed,the sup-ply voltage must decrease below the lower threshold(i.e.below V sh-H ys1)before it is turned on again.The hysteresis H ys1is provided to prevent inter-mittent operation of the device at low supply volt-ages that may have a superimposed ripple around the average value.The UV signal inhibits the outputs,putting them in three-state,but has no effect on the creation of the reference voltages for the internal compara-tors,nor on the continuous operation of the charge-pump circuits.DIAGNOSTIC LOGICThe situations that are monitored and signalled with the Diag output pin are:-current limit(OVC)in action;there are8indi-vidual current limiting circuits,two per each output,i.e.one per every output transistor;they limit the current that can be either sour-ced or sunk from each output,to a typical value of150mA,equal for all of them;-undervoltage protection(UV);-overtemperature protection(OVP);The diagnostic signal is transmitted via an open drain output(for ease of wired-or connection of several such signals)and a low level represents the presence of at least one of the monitored con-ditions,mentioned above.PROGRAMMABLE DELAYThe current limiting circuits can be requested to perform even in absence of a real fault condition, for a short period,if the load is of capacitive na-ture or if it is a filament lamp(that exhibits a very low resistance during the initial heating phase). To avoid the forwarding of misleading,short diag-nostic pulses in coincidence with the intervention of the current limiting circuits when operating on capacitive loads,a delay of about5µs is inserted on the signal path,between the”OR”of the cur-rent limit signals and its use as external diagnostic. It takes about1µs to charge(or discharge)by 24V a capacitor of5nF with a current of120mA. To implement longer delays(from the intervention of one of the current limiting circuits to the activa-tion of the diagnostic)an external capacitor can be connected between pin C3and ground(pin C3 is otherwise left open).The delay shall then be determined by the ratio of about10pF/µs,using the value of the capaci-tance connected to the pin.ANALOG INPUTS(I1,I2,I3,I4)The input stage of each channel is a high im-pedence comparator with built-in hysteresis (200mV)for high noise immunity.Each compara-tor has one input connected to all the others and tied to a common pin Ref(Pin11).If this pin is left floating an internal precise band gap voltage ref-erence(1.25V)is applied,otherwise these inputs can be externally programmed by connecting an external voltage source(from0to5V)and the current on this pin is internally limited to±20µA. The other input pin of each comparator can swing from-7to35V.For this reason it has been implemented the structure shown in Figure2and the device can also be used as line receiver.When the input voltage is negative,the current is internally limited by a15kΩresistor as shown in Figure2.High and low input thresholds can be obtained by adding and subtracting half of the hysteresis to the voltage of pin Ref(see Figure3).Figure2:Equivalent input circuitL63745/133STATE /PUSH-PULL INPUTThe input 3st/Pp is instead intended for a digital incoming signal.It has an internal threshold set at 1.26V;an internal bias circuit (10µA typical)simu-lates a high level (three-state)if the pin is discon-nected.THE SWITCHING OF THE OUTPUT STAGEThe cross conduction of the two transistors of an output stage of the L6374would be significantly noisy,because the transistors here can carry peak currents in excess of 100mA,and even more in the few nanoseconds before the current limiting circuits are really effective.Consequently the device has been designed so as to avoid such cross conduction.At every switching transition,first of all the transistor in conduction is turned off.Then,after a safe inter-val of around 200ns,the other transistor is turned on.When analyzing the switching cycle,and the as-sociated switching times,it is useful to identify some subsequent phases:-delay from the input pin to the output reaction;-off transition in the output stage;-dead time;-on transition in the output stage.Figure 4helps understand such sequence.InFigure 4:V S =35V,350Ω connected to V S /2.V refV iV sV outH ys2H ys222D94IN073Figure 3:Input Comparator ThresholdL63746/13fact,with a purely resistive load connected to V s/2 no parasitic elements interfere significantly.The waveform can be significantly less easy to in-terpret if the load has not the perfect symmetry of that case,as showed below.For instance,it is enough to connect the resistive load to ground,or to V s–as figure5and6–show to hide some of the switching phases described.If the load is connected to ground,the waveform stays stuck to ground as long as the output stage is in high impedance;viceversa when the load is connected to V s the waveform will linger close to the supply voltage as long as possible.If an output load made of an inductor and a resis-tor in series is used,the inductive kick at the be-ginning of every output transition generates the equivalent effect of an”anticipated”switching when the inductor can discharge;while the switching looks”delayed”if the output transition tends to initiate a charging phase(see figure7). With a load almost free from parasitic elements, the waveforms resemble the ones of the purely resistive cases.With a real,more composite load,the effect of the inductive kick in comparison to the resistive load, would be more apparent.With a capacitor and a resistor in parallel as a load,another type of waveform can be seen(re-ported in figure8).As long as the output stage stays in the transient high impedance state,the output voltage will fol-low the classic exponential law of an RC relaxa-tion.As soon as the other transistor is switched on and takes charge,the waveform is quickly forcibly brought to its steady state value.From the above it is possible to see how the switching times,inherently very fast,of the output stages,may be difficult to identify in a waveform if the output load is not accurately taken into con-sideration.Figure9show typical switching waveform for in-puts and outputs.Figure5:V S=35V,350Ω connected to ground.L63747/13L6374Figure6.V S=35V,350Ω connected to V S.Figure7.V S=35V,350Ω &1mH connected to ground. 8/13Figure 8:V S =35V,350Ω ||1nF connected to ground.50%50%t dft drt90%90%10%10%t ft rtInOutD94IN074Figure 9:Switching Waveforms.L63749/13APPLICATION NOTEIt is recommended not to leave the Ref pin (pin11)floating:if not used with an external volt-age reference,it is better to connect an external capacitor(of at least10nF)between this pin and ground.This capacitor filters the voltage reference against voltage spikes that can be generated by the com-mutation of the output stages.This is very common using capacitive loads:in fact,the initial transient of such loads behaves like a short circuit,so the current flowing through the outputs presents very high spikes. Moreover,if the device is used as a line receiver.(i.e.the input signals can go below ground)it is required not to leave the Ref pin(pin11)floating: in this case,the pin can be connected to ground or to a fixed external voltage reference.L6374 10/13L6374DIP20PACKAGE MECHANICAL DATAmm inch DIM.MIN.TYP.MAX.MIN.TYP.MAX.a10.510.020B0.85 1.400.0330.055b0.500.020b10.380.500.0150.020D24.800.976E8.800.346e 2.540.100e322.860.900F7.100.280I 5.100.201L 3.300.130Z 1.270.05011/13SO20PACKAGE MECHANICAL DATADIM.mm inchMIN.TYP.MAX.MIN.TYP.MAX.A 2.650.104a10.10.30.0040.012 a2 2.450.096 b0.350.490.0140.019 b10.230.320.0090.013 C0.50.020c145(typ.)D12.613.00.4960.512 E1010.650.3940.419e 1.270.050e311.430.450F7.47.60.2910.299 L0.5 1.270.0200.050 M0.750.030 S8(max.)L637412/13L6374Information furnished is believed to be accurate and reliable.However,SGS-THOMSON Microelectronics assumes no responsibility for the consequences of use of such information nor for any infringement of patents or other rights of third parties which may result from its use.No license is granted by implication or otherwise under any patent or patent rights of SGS-THOMSON Microelectronics.Specifications men-tioned in this publication are subject to change without notice.This publication supersedes and replaces all information previously supplied.

with 3STATE OUTPUTS NON INVERTING fabricated with sub-micron silicon gate and five-layer metal wiring C 2MOS technology.It is ideal for low power and very high speed 2.3to 3.6V applications;it can be interfaced to 3.6V signal environment for both inputs and outputs.These 16bit D-TYPE flip-flops are controlled by two clock inputs (nCK)and two output enable inputs (nOE).On the positive transition of the (nCK),the nQ outputs will be set to the logic state that were setup at the nD inputs.While the (nOE)input is low,the 8outputs (nQ)will be in a normal state (HIGH or LOW logic level)and while high level the outputs will be in a high impedance state.Any output control does not affect the internal operation of flip flops;that is,the old data can be retained or the new data can be entered even while the outputs are off.Bus hold on data inputs is provided in order to eliminate the need for external pull-up or pull-down resistor.74VCXH16374LOW VOLTAGE CMOS 16-BIT D-TYPE FLIP-FLOP

The device is byte controlled with each byte function-ing identically, but independent of the other. The control pins can be shorted together to obtain full 16-bit operation.Each clock has a buffered clock and buffered Output Enable common to all flip-flops within that byte. The description which follows applies to each byte. Each flip-flop will store the state of their individual I inputs that meet the setup and hold time requirements on the LOW-to-HIGH Clock (CP n ) transition. With the Output Enable (OE n ) LOW,the contents of the flip-flops are available at the outputs.When OE n is HIGH, the outputs go to the high impedance state.

The device is byte controlled. A buffered clock (CP) and Output Enable (OE) are common to each byte and can be shorted together for full 16-bit operation.The LCXH16374 is designed for low voltage (2.5V or 3.3V)V CC applications.The LCXH16374 is fabricated with an advanced CMOS technology to achieve high speed operation while maintain-ing CMOS low power dissipation.The LCXH16374 data inputs include active bushold cir-cuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level.Featuress 5V tolerant control inputs and outputs s 2.3V–3.6V V CC specifications provided s 6.2 ns t PD max (V CC = 3.3V), 20 µA I CC max s Bushold on inputs eliminating the need for external pull-up/pull-down resistors s Power down high impedance outputs s ±24 mA output drive (V CC = 3.0V)s Implements patented noise/EMI reduction circuitry s Latch-up performance exceeds 500 mA s ESD performance:Human body model > 2000V Machine model > 200Vs Also packaged in plastic Fine-Pitch Ball Grid Array (FBGA)Ordering Code:Note 1: Ordering code “G ” indicates Trays.Note 2: Devices also available in Tape and Reel.

The device is byte controlled with each byte func-tioning identically, but independent of the other. The control pins can be shorted together to obtain full 16-bit operation.Each byte has a buffered clock and buffered Output Enable common to all flip-flops within that byte. The description which follows applies to each byte. Each flip-flop will storethe state of their individual D inputs that meet the setup and hold time requirements on the LOW-to-HIGH Clock (CP n )transition. With the Output Enable (OE n ) LOW, the con-tents of the flip-flops are available at the outputs. When OE n is HIGH, the outputs go to the high impedance state.Operation of the OE n input does not affect the state of the flip-flops.Logic DiagramsByte 1 (0:7)Byte 2 (8:15)Please note that this diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays. 474L C X H 16374Absolute Maximum Ratings (Note 3)Recommended Operating Conditions (Note 5)Note 3: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed.
