NLVHC1GT66

SPST (NO) Normally Open

Analog Switch

The MC74VHC1GT66, NLVHC1GT66 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

The MC74VHC1GT66, NLVHC1GT66 is compatible in function to

a single gate of the High Speed CMOS MC74VHCT4066 and the

metal−gate CMOS MC14066. The device has been designed so that

analog switches.

The newer NLVHC1GT66 offers the same functionality in a

1.2x1.0x0.55 mm UDFN6 package.

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 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.

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, NLVHC1GT66 to be used to interface 5 V circuits

to 3 V circuits.
