Overview
The 74HC373PW-Q100,118 is an octal D-type transparent latch with 3-state outputs, manufactured by Nexperia USA Inc. This device is part of the 74HC series and is designed to operate within a wide range of applications, including automotive systems due to its AEC-Q100 qualification. The latch features both latch enable (LE) and output enable (OE) inputs, allowing for flexible control over data storage and output states. When the LE input is high, the latches are transparent, and the output follows the input data. When the LE input goes low, the latches store the data present at the inputs at the time of the transition. A high state on the OE input causes the outputs to enter a high-impedance state, independent of the latch state.
