Product Introduction

Overview

The 74HCT4851PW-Q100 is an 8-channel analog multiplexer/demultiplexer designed by Nexperia. This high-speed Si-gate CMOS device is specified in compliance with JEDEC standard no. 7A and is particularly suited for automotive applications due to its robust features and compliance with the Automotive Electronics Council (AEC) standard Q100 (Grade 1).

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 notable for its injection-current effect control, which allows signals at disabled analog input channels to exceed the supply voltage without affecting the signal of the enabled analog channel.
