1. General description

The 74LVC1G79 is a single positive-edge triggered D-type flip-flop. Data at the D-input that meets

the set-up and hold time requirements on the LOW-to-HIGH clock transition will be stored in the

flip-flop and appear at the Q output. Inputs can be driven from either 3.3 V or 5 V devices. This

feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

This device is fully specified for partial power down applications using IOFF. The IOFF circuitry

disables the output, preventing the potentially damaging backflow current through the device when

it is powered down.
