Overview
The 74HC4851BQ-Q100,11 is an 8-channel analog multiplexer/demultiplexer produced by Nexperia USA Inc. This high-speed Si-gate CMOS device is specified in compliance with JEDEC standard no. 7A and is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for use in automotive applications.
The device features three digital select inputs (S0 to S2), an active-LOW enable input (E), eight independent inputs/outputs (Y0 to Y7), and a common input/output (Z). It is designed to handle signals at disabled analog input channels that exceed the supply voltage without affecting the signal of the enabled analog channel, thanks to its injection-current effect control.
