SINGLE SCHMITT-TRIGGER

INVERTER

 DESCRIPTION

The UTC U74LVC1G14 is a single Schmitt-trigger inverter, it

provides the function Y= A.

The device have different input threshold levels for positive-

going (VT+) and negative-going(VT-) signals because of the

Schmitt-trigger action in the input.

This device has power-down protective circuit, preventing

device destruction when it is powered down.

 FEATURES

* Operation Voltage Range: 1.65V~5.5V

* Low Power Current: ICC=10μA(Max)

* 24mA output drive(VCC=3.0V)

* High Noise Immunity

* Power Down Protection
