HEX SCHMITT-TRIGGER
INVERTERS
DESCRIPTION
The U74LVC14A devices contain six independent inverters with
Schmitt-trigger action which perform the Boolean function Y=
positive logic.
in
A
This device has power-down protective circuit preventing destruction of
the device when it is powered down.
FEATURES
* Operate From 1.65V to 3.6V
* Inputs Accept Voltages to 5.5V
* IOFF Supports Partial-Power-Down Mode
* Low Power Dissipation
* Max tPD of 6.4 ns at 3.3V
