E, S FaxBack 408-970-56004-9APPLICATIONS Power SuppliesPower supply flexibility is a useful feature of the DG641/642/643 series. It can be operated from a single positive supply (V+) if required (V– connected to ground). Note that the analog signal must not exceed V– by more than –0.3 V to prevent forward biasing the substrate p-n junction. The use of a V– supply has a number of advantages:1.It allows flexibility in analog signal handling, i.e., with V– =–5 V and V+ = 12 V; up to "5-V ac signals can be controlled.2.The value of on capacitance [C S(on)] may be reduced. Aproperty known as ‘the body-effect’ on the DMOS switch devices causes various parametric effects to occur. One of these effects is the reduction in C S(on) for an increasing V body-source. Note however that to increase V–normally requires V+ to be reduced (since V+ to V– = 21 V max.). A reduction in V+ causes an increase in r DS(on), hence a compromise has to be achieved. It is also useful to note that tests indicate that optimum video linearity performance (e.g., differential phase and gain) occurs when V– is around –3 V.3.V– eliminates the need to bias the analog signal usingpotential dividers and large coupling capacitors. DecouplingIt is an established rf design practice to incorporate sufficient bypass capacitors in the circuit to decouple the power supplies to all active devices in the circuit. The dynamic performance of the DG641/642/643 series is adversely affected by poor decoupling of power supply pins. Also, of even more significance, since the substrate of the device is connected to the negative supply, adequate decoupling of this pin is essential. Suitable decoupling capacitors are 1- to 10-m F tantalum bead, plus 10- to 100-nF ceramic or polyester. Rules:1.Decoupling capacitors should be incorporated on allpower supply pins (V+, V–). (See Figure 7).2.They should be mounted as close as possible to thedevice pins.3.Capacitors should be of a suitable type with good highfrequency characteristics – tantalum bead and/or ceramic disc types are adequate.++–3 VGNDs+15 VDG64XV+V–S1S2S3S4D1D2D3D4C1C2C1C2C1 = 10 m F TantalumC2 = 0.1 m F CeramicFIGURE 7.Supply DecouplingBoard LayoutPCB layout rules for good high frequency performance must also be observed to achieve the performance boasted by these analog switches. Some tips for minimizing stray effects are:e extensive ground planes on double sided PCB,separating adjacent signal paths. Multilayer PCB is even better.2.Keep signal paths as short as practically possible, with allchannel paths of near equal length.3.Careful arrangement of ground connections is also veryimportant. Star connected system grounds eliminate signal current, flowing through ground path parasitic resistance, from coupling between channels.Figure 8 shows a 4-channel video multiplexer using a DG641.In Figure 9, two coax cables terminated on 75 W bring two video signals to the DG642 switch. The two drains tied together lower the on-state capacitance. An Si582 video amplifier drives a double terminated 75-W cable. The double terminated coax cable eliminates line reflections.。

DG421/DG423/DG425Improved Low-Power,CMOS Analog Switches with Latches________________________________________________________________Maxim Integrated Products1_________________Pin Configurations__Functional Diagrams/Truth T ablesCall toll free 1-800-998-8800 for free samples or literature.19-0137; Rev 1; 3/94_______________General DescriptionMaxim’s redesigned DG421/DG423/DG425 monolithic analog switches now feature guaranteed on-resistance matching (3Ωmax) between switches and on-resistance flatness over the signal range (4Ωmax). These low on-resistance switches (20Ωtyp) conduct equally well in both directions. They guarantee a low charge injection of 15pC maximum and an ESD tolerance of 2000V minimum per Method 3015.7. Off leakage current over temperature has also been reduced (less than 5nA at +85°C).The DG421/DG423/DG425 are precision, dual CMOS switches with latchable logic inputs that simplify inter-facing with microprocessors (µPs). The single-pole/single-throw DG421 and double-pole/single-throw DG425 are normally open dual switches. The dual, single-pole/double-throw DG423 has two normally open and two normally closed switches. Fast switching times (175ns for t ON and 145ns for t OFF ) and low power consumption (35µW max) make these parts ideal for battery-powered applications requiring µP-compatible switches. Operation is from a single +10V to +30V supply,or bipolar ±4.5V to ±20V supplies. Fabricated with the same 44V silicon-gate process, these switches have rail-to-rail signal handling capabilities._______________________ApplicationsSample-and-Hold Circuits ModemsFax MachinesTest Equipment Battery-Operated SystemsPBX, PABX Guidance and Control Systems Military RadiosAudio Signal RoutingCommunication Systems______________________New Featureso Plug-In Upgrades for Industry-Standard DG421/DG423/DG425o Improved r (DS)ON Match Between Channels (3Ωmax)o Guaranteed r FLAT(ON)Over Signal Range (4Ωmax)o Improved Charge Injection (15pC max)o Improved Off Leakage Current Over Temperature (<5nA at +85°C)o Withstands Electrostatic Discharge (2000V min)per Method 3015.7__________________Existing Featureso Low r DS(ON)(35Ωmax)o Single-Supply Operation +10V to +30V Bipolar-Supply Operation ±4.5V to ±20V o Low Power Consumption (35µW max)o Rail-to-Rail Signal Handling Capability o TTL/CMOS-Logic Compatible______________Ordering Information*Contact factory for dice specifications.**Contact factory for availability and processing to MIL-STD-883B.D G 421/D G 423/D G 425Improved Low-Power,CMOS Analog Switches with LatchesVoltage Referenced to V-V+............................................................44V GND .........................................................25V V L ..................................(GND - 0.3V) to (V+ + 0.3V)Digital Inputs, V S , V D (Note 1)..............(V- - 2V) to (V+ + 2V)Current (any terminal, except S or D).................................30mA Continuous Current, S or D.................................................20mA Peak Current, S or D (pulsed at 1ms, 10% duty cycle max)...100mAContinuous Power Dissipation (T A = +70°C)16-Pin Plastic DIP (derate 10.53mW/°C above +70°C)...842mW 20-Pin PLCC (derate 10.00mW/°C above +70°C).....800mW 16-Pin CERDIP (derate 10.00mW/°C above +70°C) ...800mW Operating Temperature RangesDG42_C_..........................................0°C to +70°C DG42_D_ .......................................-40°C to +85°C DG42_A_ ......................................-55°C to +125°C Storage Temperature RangesDG42_C_/DG42_D_ ...........................-65°C to +125°C DG42_A_ .....................................-65°C to +150°C Lead Temperature (soldering, 10sec)....................+300°CELECTRICAL CHARACTERISTICS(V+ = 15V, V- = -15V, V L = +5V, GND = 0V, V INH = +2.4V, V INL = +0.8V, T A = T MIN to T MAX , unless otherwise noted.)Stresses beyond those listed under "Absolute Maximum Ratings " may cause permanent damage to the device.

In either case, analog signals ranging from V+to V- can be switched. The Typical Operating Characteristics graphs illustrate typical analog-signal and supply-voltage on-resistance variations. The usual on-resistance temperature coefficient is 0.5%/°C (typ).Logic InputsThese devices operate with a single positive supply or with bipolar supplies. They maintain TTL compatibility with supplies anywhere in the ±4.5V to ±20V range as long as V L = +5V. If V L is connected to V+ or another supply at voltages other than +5V, the devices will operate at CMOS-logic-level inputs.Overvoltage ProtectionProper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maxi-mum ratings because stresses beyond the listed rat-ings may cause permanent damage to the devices.Always sequence V+ on first, followed by V L , V-, and logic inputs. If power-supply sequencing is not possi-ble, add two small, external signal diodes in series with supply pins for overvoltage protection (Figure 1).Adding diodes reduces the analog signal range to 1V below V+ and 1V above V-, without affecting low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+and V- should not exceed +44V.D G 421/D G 423/D G 425Improved Low-Power,CMOS Analog Switches with Latches 6_______________________________________________________________________________________Figure 2.

当筒体内装有机油后，可借助缓冲机构消除钩身上下运动时产生的轴向冲击，防止卸扣时钻杆的反弹振动及随着发生对钻杆接头螺纹的损坏，机油也同时润滑轴承(21)、制动装置(24)及其它零件。

筒体上部装有安全定位装置，该定位装置由安装在筒体上端的弹簧(11)和由弹簧推动的定位盘(10)组成，定位盘可上下滑动但不能转动。

当提升空吊卡时，定位盘与吊环座的环形面相接触，借助弹簧在环形面之间产生的摩擦力，来阻止钩身的转动，这样可避免吊卡转位，便于井架工操作吊卡。

当悬挂有钻杆柱时，定位盘与吊环座脱开，不起定位作用。

钩身就可以任意转动，就不会有转动游动滑车的倾向。

The DG456 has two normally closed and two normally open switches.These are high voltage switches that are fully specified with dual supplies at ± 5 V and ± 15 V and a single supply of 12 V. Fast switching speeds coupled with high signal bandwidth makes these parts suitable for video switching applications.All digital inputs have 0.8 V and 2.4 V logic thresholds ensuring low voltage TTL/CMOS compatibility. Each switch conducts equally well in both directions when on and can handle an input signal range that extends to the supply voltage rails.The DG454 DG455 and DG456 are pin compatible with the DG411, DG412 and DG413, except they require no V L supply.FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATIONTRUTH TABLELogic DG454DG4550ON OFF 1OFFONTRUTH TABLELogic SW 1, SW 4SW 2, SW 30OFF ON 1ONOFFVishay SiliconixDG454/DG455/DG456Notes:a. - 40 °C to 85 °C datasheet limits apply.Notes:a.
