Overview
The SN74AHC1G32DCKT is a single 2-input positive-OR gate logic IC manufactured by Texas Instruments. This device performs the Boolean function Y = A + B in positive logic, making it suitable for a wide range of digital logic applications. It is part of the 74AHC series, known for its advanced high-speed CMOS technology, which offers low power consumption and high-speed operation.
The device is available in several package types, including DBV (SOT-23), DCK (SC70), and DRL (SOT), making it versatile for different design requirements. However, it is important to note that Texas Instruments has announced the discontinuation of this device, with a lifetime-buy period in effect, and it is not recommended for new designs.
