Overview
The SN74LVC1G17DBVRG4 is a single Schmitt-trigger buffer produced by Texas Instruments. This device is designed for operation over a wide voltage range of 1.65 V to 5.5 V, making it versatile for various applications. It features a single buffer that performs the Boolean function Y = A, with the added benefit of Schmitt-trigger inputs that provide hysteresis, which helps in handling noisy or slow input signals.
The device is available in several ultra-small package options, including the DPW package with a body size of 0.8 mm × 0.8 mm, which is particularly useful for saving board space in compact designs.
