Overview
The 74HC4851PW-Q100,11 from Nexperia USA Inc. is an 8-channel analog multiplexer/demultiplexer designed for high-speed applications. This device is part of the 74HC/74HCT family and is compliant with JEDEC standard no. 7A. It features three digital select inputs (S0 to S2) and an active-LOW enable input (E), allowing for the selection of one of eight independent inputs/outputs (Y0 to Y7) or a common input/output (Z). The device is particularly suited for automotive applications due to its qualification to the Automotive Electronics Council (AEC) standard Q100 (Grade 1).
