register utilizes advancedsilicon-gate CMOS technology Along with the low powerconsumption and high noise immunity of standard CMOSintegrated circuits it has the ability to drive15LS-TTLloads This circuit also features operating speeds compara-ble to the equivalent low power Schottky deviceThe MM54HC299 MM74HC299features multiplexed in-puts outputs to achieve full8-bit data handling in a single20-pin package Due to the large output drive capability andTRI-STATE feature this device is ideally suited for interfac-ing with bus lines in a bus oriented systemTwo function select inputs and two output control inputs areused to choose the mode of operation as listed in the func-tion table Synchronous parallel loading is accomplished bytaking both function select lines S0and S1high This placesthe TRI-STATE outputs in a high impedance state whichpermits data applied to the input output lines to be clockedinto the register Reading out of the register can be donewhile the outputs are enabled in any mode A direct overrid-ing CLEAR input is provided to clear the register whetherthe outputs are enabled or disabledThe54HC 74HC logic family is functionally as well as pinoutcompatible with the standard54LS 74LS logic family Allinputs are protected from damage due to static discharge byinternal diode clamps to V CC and groundFeaturesY Typical operating frequency40MHzY Typical propagation delay 20nsY Low quiescent current 80m A maximum(74HC)Y High output drive for bus applicationsY Low quiescent current 1m A maximum Connection DiagramDual-In-Line PackageTL F 5207–1Order

TECHNICAL DATA3868-Bit Bidirectional Universal Shift Register with Parallel I/OHigh-Speed Silicon-Gate CMOSThe IN74AC299 is identical in pinout to the LS/ALS299,HC/HCT299. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs.The IN74AC299 features a multiplexed parallel input/output data port to achieve full 8-bit handling in a 20 pin package. Due to the large output drive capability and the 3-state feature, this device is ideally suited for interface with bus lines in a bus-oriented system.Two Mode-Select inputs and two Output Enable inputs are used to choose the mode of operation as listed in the Function Table.Synchronous parallel loading is accomplished by taking both Mode-Select lines, S 1 and S 2, high. This places the outputs in the high-impedance state, which permits data applied to the data port to be clocked into the register. Reading out of the register can be accomplished when the outputs are enabled. The active-low asynchronous Reset overrides all other inputs.• Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2.0 to 6.0 V• Low Input Current: 1.0 µA; 0.1 µA @ 25°C• High Noise Immunity Characteristic of CMOS Devices • Outputs Source/Sink 24 mAIN74AC299LOGIC DIAGRAMPIN 20=V CC PIN 10 = GNDPIN ASSIGNMENTIN74AC299387MAXIMUM RATINGS *Symbol ParameterValue Unit V CC DC Supply Voltage (Referenced to GND)-0.5 to +7.0V V IN DC Input Voltage (Referenced to GND)-0.5 to V CC +0.5V V OUT DC Output Voltage (Referenced to GND)-0.5 to V CC +0.5V I IN DC Input Current, per Pin±20mA I OUT DC Output Sink/Source Current, per Pin ±50mA I CC DC Supply Current, V CC and GND Pins ±50mA P D Power Dissipation in Still Air, Plastic DIP+ SOIC Package+750500mW Tstg Storage Temperature-65 to +150°C T LLead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package)260°C*Maximum Ratings are those values beyond which damage to the device may occur.Functional operation should be restricted to the Recommended Operating Conditions.+Derating - Plastic DIP: - 10 mW/°C from 65° to 125°CSOIC Package: : - 7 mW/°C from 65° to 125°CRECOMMENDED OPERATING CONDITIONSSymbol ParameterMin Max Unit V CC DC Supply Voltage (Referenced to GND)2.0 6.0V V IN , V OUTDC Input Voltage, Output Voltage (Referenced to GND)0V CC V T J Junction Temperature (PDIP)140°C T A Operating Temperature, All Package Types -40+85°C I OH Output Current - High -24mA I OL Output Current - Low 24mA t r , t fInput Rise and Fall Time *(except Schmitt Inputs)V CC =3.0 V V CC =4.5 V V CC =5.5 V0001504025ns/V*V IN from 30% to 70% V CCThis device contains protection circuitry to guard against damage due to high static voltages or electricfields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, V IN and V OUT should be constrained to the range GND ≤(V IN or V OUT )≤V CC .Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V CC ).Unused outputs must be left open.IN74AC299388DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND)V CCGuaranteed Limits Symbol Parameter Test Conditions V 25 °C -40°C to 85°C Unit V IHMinimum High-Level Input Voltage V OUT =0.1 V or V CC -0.1 V3.04.55.5 2.13.153.85 2.13.153.85VV IL Maximum Low -Level Input Voltage V OUT =0.1 V or V CC -0.1 V 3.04.55.50.91.351.650.91.351.65VV OH Minimum High-Level Output VoltageI OUT ≤ -50 µA3.04.55.5 2.94.45.4 2.94.45.4V*V IN =V IH or V IL I OH =-12 mA I OH =-24 mA I OH =-24 mA3.04.55.5 2.563.864.86 2.463.764.76V OLMaximum Low-Level Output VoltageI OUT ≤ 50 µA3.04.55.50.10.10.10.10.10.1V *V IN = V IH or V IL I OL =12 mA I OL =24 mA I OL =24 mA3.04.55.50.360.360.360.440.440.44I IN Maximum Input Leakage Current V IN =V CC or GND 5.5±0.1±1.0µA I OZMaximum Three-State Leakage CurrentV IN (OE)= V IH or V IL V IN =V CC or GND V OUT =V CC or GND 5.5±0.6±6.0µA I OLD +Minimum Dynamic Output Current V OLD =1.65 V Max 5.575mA I OHD +Minimum Dynamic Output Current V OHD =3.85 V Min 5.5-75mA I CCMaximum Quiescent Supply Current (per Package)V IN =V CC or GND5.58.080µA*All outputs loaded; thresholds on input associated with output under test.+Maximum test duration 2.0 ms, one output loaded at a time.Note: I IN and I CC @ 3.0 V are guaranteed to be less than or equal to the respective limit @ 5.5 V V CCIN74AC299389AC ELECTRICAL CHARACTERISTICS (C L =50pF,Input t r =t f =3.0 ns)V CC *Guaranteed Limits SymbolParameterV25 °C -40°C to 85°C UnitMinMaxMin Maxf max Maximum Clock Frequency (Figure 1) 3.35.0901*******MHz t PLH Propagation Delay, Clock to Q A ’ or Q H ’(Figure 1)3.35.08.55.520.514.07.04.522.015.0ns t PHL Propagation Delay, Clock to Q A ’ or Q H ’(Figure 1)3.35.08.55.521.514.57.05.023.016.0ns t PLH Propagation Delay, Clock to Q A thru Q H (Figure 1)3.35.09.06.020.514.57.55.022.516.0ns t PHL Propagation Delay, Clock to Q A thru Q H (Figure 1)3.35.010.06.523.016.08.56.024.517.5ns t PHL Propagation Delay, Reset to Q A ’ or Q H ’(Figure 2)3.35.09.05.522.515.57.55.025.017.0ns t PHL Propagation Delay, Reset to Q A thru Q H (Figure 2)3.35.09.05.521.515.07.55.024.016.5ns t PZH Propagation Delay , OE1, OE2 to Q A thru Q H (Figure 3)3.35.07.04.518.012.5 6.04.019.513.5ns t PZL Propagation Delay , OE1, OE2 to Q A thru Q H (Figure 3)3.35.07.05.018.012.5 6.04.020.514.0ns t PHZ Propagation Delay , OE1, OE2 to Q A thru Q H (Figure 3)3.35.0 6.53.518.514.05.53.019.515.0ns t PLZ Propagation Delay , OE1, OE2 to Q A thru Q H (Figure 3)3.35.0 5.53.517.012.5 4.52.019.013.5ns C INMaximum Input Capacitance5.04.54.5pF Typical @25°C,V CC =5.0 VC PDPower Dissipation Capacitance 170pF*Voltage Range 3.3 V is 3.3 V ±0.3 V Voltage Range 5.0 V is 5.0 V ±0.5 VIN74AC299390TIMING REQUIREMENTS (C L =50pF,Input t r =t f =3.0 ns)V CC *Guaranteed Limits Symbol ParameterV 25 °C -40°C to 85°C Unit t su Minimum Setup Time, Mode Select S1 or S2to Clock (Figure 4)3.35.08.05.08.55.5ns t su Minimum Setup Time, Data Inputs P A thru P H to Clock (Figure 4)3.35.0 5.53.5 6.04.0ns t su Minimum Setup Time, Data Inputs S A , S H to Clock (Figure 4)3.35.0 6.54.07.04.5ns t h Minimum Hold Time, Clock to Mode Select S1 or S2 (Figure 4)3.35.00.51.00.51.0ns t h Minimum Hold Time, Clock to Data Inputs P A thru P H (Figure 4)3.35.001.001.0ns t h Minimum Hold Time, Clock to Data Inputs S A , S H (Figure 4)3.35.001.00.51.0ns t rec Minimum Recovery Time, Reset Inactive to Clock (Figure 2)3.35.0 1.51.5 1.51.5ns t w Minimum Pulse Width, Clock (Figure 1) 3.35.04.53.55.03.5ns t wMinimum Pulse Width, Reset (Figure 2)3.35.04.53.55.03.5ns*Voltage Range 3.3 V is 3.3 V ±0.3 V Voltage Range 5.0 V is 5.0 V ±0.5 VIN74AC299391Z = high impedance D = data on serial inputWhen one or both output controls are high the eight input/output terminals are disabled to the high-IN74AC299392Figure 1.
