Overview
The SN74LVC3G17DCTRE4 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 and is designed to perform the Boolean function Y = A. It features three independent buffers, each with Schmitt trigger action, which provides different input threshold levels for positive-going and negative-going signals. The device is suitable for partial-power-down applications and includes Ioff circuitry to prevent damaging current backflow when powered down. It is available in the NanoFree™ package, which is a bare die package technology offering the smallest possible package size.
