Overview
The SN74LVC1G97DBVRE4 is a configurable multiple-function gate produced by Texas Instruments. This device is designed to operate over a wide supply voltage range of 1.65 V to 5.5 V, making it versatile for various applications. It features eight patterns of 3-bit input that determine the output state, allowing users to choose from nine specific logic functions such as MUX, AND, OR, NAND, NOR, inverter, and noninverter. The device includes Schmitt action, which may result in different input threshold levels for positive-going and negative-going signals. It is also fully specified for partial-power-down applications using Ioff circuitry, which disables the outputs to prevent damaging current backflow when the device is powered down.
