Overview
The SN74LVC3G17DCTR, produced by Texas Instruments, is a triple Schmitt-trigger buffer designed for operation over a wide voltage range of 1.65 V to 5.5 V. This device is part of the LVC (Low-Voltage CMOS) family and is available in various packages, including the SSOP (Shrink Small Outline Package) and VSSOP (Very Thin Shrink Small Outline Package). The SN74LVC3G17 performs the Boolean function Y = A and functions as three independent buffers, each with Schmitt-trigger action, which provides different input threshold levels for positive-going and negative-going signals. This feature enhances noise immunity and stability in digital circuits.
