vht66?1/6 the MC74VHC1GT66 is an advanced high speed cmos bilateral analog switch fabricated with silicon gate cmos technology. it achieves high speed propagation delays and low on resistances while maintaining low power dissipation. this bilateral switch co ntrols analog and digital voltages that may vary across the full power?supply range (from vcc to gnd). the MC74VHC1GT66 is compatible in function to a single gate of the very high speed cmos mc74vhct4066. the device has been designed so that the on resistances (ron) are much lower and more linear over input voltage. the on/off control input is compatible with ttl?type input thresholds allowing the device to be used as a logic?level translator from 3.0 v cmos logic to 5.0 v cmos logic or from 1.8 v cmos logic to 3.0 v cmos logic while operating at the high?voltage power sup ply. the input protection circuitry on this device allows overvoltage tolerance on the input, which provides protection when voltages of up to 7 v are applied, regardless of the supply voltage. this allows the MC74VHC1GT66 to be used to interface 5 v circuits to 3 v circu its. high speed: t pd = 20 ns (typ) at v cc = 5 v low power dissipation: i cc = 2 a (max) at t a = 25c diode protection provided on inputs and outputs improved linearity and lower on resistance over input voltage on/off control input has ovt analog switch ve d ve d 1 3 2 4 5 sot?23/tsop?5/sc?59 dt suffix case 483 sc?70/sc?88a/sot?353 df suffix case 419a 1 3 2 4 5 marking diagrams pin 1 d = date code pin 1 d = date code figure 1. pinout (top view) figure 2. logic symbol pin assignment 1 in/out x a 2 out/in y a 3 gnd 4 on/off control 5v cc function table on / off control input state analog switch loff hon ordering information see detailed ordering and shipping information in the package dimensions section on page 6 of this data sheet.
