Overview
The SN74LVC3G17DCTRG4 is a triple Schmitt-trigger buffer produced by Texas Instruments. This device operates within a voltage range of 1.65 V to 5.5 V, making it versatile for various applications. It contains three independent buffers that perform the Boolean function Y = A, with the added benefit of Schmitt action, which provides different input threshold levels for positive-going (VT+) and negative-going (VT–) signals. The device is available in several package options, including SSOP, VSSOP, and DSBGA, and is part of the NanoFree™ package technology, which minimizes package size.
