MC74VHC1GT66 SPST (NO) Normally Open Analog Switch The MC74VHC1GT66 is a Single Pole Single Throw (SPST) analog switch. It achieves high speed propagation delays and low ON resistances while maintaining low power dissipation. This bilateral switch controls analog and digital voltages that may vary across the http://onsemi.com full power−supply range (from V to GND). CC MARKING The MC74VHC1GT66 is compatible in function to a single gate of DIAGRAMS the High Speed CMOS MC74VHCT4066 and the metal−gate CMOS MC14066. The device has been designed so that the ON resistances 5 SC−88A (RON) are much lower and more linear over input voltage than RON of 5 DF SUFFIX M VE M(cid:2) the metal−gate CMOS or High Speed CMOS analog switches. 1 CASE 419A (cid:2) The ON/OFF Control input is compatible with TTL−type input 1 thresholds allowing the device to be used as a logic−level translator from 3 V CMOS logic to 5 V CMOS logic or from 1.8 V CMOS logic to 3 V CMOS logic while operating at the high−voltage power supply. 5 TSOP−5 The input protection circuitry on this device allows overvoltage 5 VE M(cid:2) DT SUFFIX tolerance on the input, which provides protection when voltages of up (cid:2) CASE 483 1 to 7 V are applied, regardless of the supply voltage. This allows the 1 MC74VHC1GT66 to be used to interface 5 V circuits to 3 V circuits.
