Overview
The SN74LVC2G17DBVT is a dual Schmitt-Trigger buffer produced by Texas Instruments. This device is designed for operation over a wide voltage range from 1.65 V to 5.5 V, making it versatile for various applications. It features two independent buffers that perform the Boolean function Y = A, with the added benefit of Schmitt-Trigger inputs which provide hysteresis, helping to stabilize the input signals against noise.
The device is available in several package options, including SOT-23, SC70, SON, and DSBGA, which cater to different design and space requirements. The SN74LVC2G17DBVT is part of the LVC (Low-Voltage CMOS) family, known for its low power consumption and high performance.
