Overview
The SN74LVC1G17DRLRG4, produced by Texas Instruments, is a single Schmitt-trigger buffer designed for a wide range of voltage operations. This device operates from 1.65 V to 5.5 V, making it versatile for various applications. It performs the Boolean function Y = A and features Schmitt-trigger inputs, which provide different input threshold levels for positive-going and negative-going signals. The device is available in several ultra-small package options, including the DPW package with a 0.64 mm square footprint, which saves significant board space while maintaining a traditional manufacturing-friendly lead pitch of 0.5 mm.
