Overview
The SN74LVC1G17-Q1 is a single Schmitt-trigger buffer designed by Texas Instruments. This device operates within a wide voltage range of 1.65 V to 5.5 V, making it versatile for various applications. It contains one buffer and performs the Boolean function Y = A, with the Schmitt trigger action providing different input threshold levels for positive-going and negative-going signals. The device is fully specified for partial-power-down applications using Ioff, which disables the outputs to prevent damaging current backflow when the device is powered down.
