8 Detailed Description

8.1 Overview

This configurable multiple-function gate is designed for 1.65-V to 5.5-V VCC operation.

The SN74LVC1G97 device features configurable multiple functions. The output state is determined by eight

patterns of 3-bit input. The user can choose variations of common logic functions, like AND, OR, and NOT.

All inputs can be connected to VCC or GND.

This device functions as an independent gate, but because of Schmitt action, it may have different input

threshold levels for positive-going (VT+) and negative-going (VT–) signals.

This device is fully-specified for partial-power-down applications using Ioff. The Ioff circuitry disables the

outputs, preventing damaging current backflow through the device when it is powered down.

8.3 Feature Description

The SN74LVC1G97 device has a wide operating VCC range of 1.65 V to 5.5 V, which allows use in a broad

range of systems. The 5.5-V I/Os allow down translation and also allow voltages at the inputs when VCC = 0 V.
