Overview
The 74HC4851D-Q100,118 is a high-speed Si-gate CMOS device produced by Nexperia USA Inc. It is an 8-channel analog multiplexer/demultiplexer that complies with JEDEC standard no. 7A and is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1). This component is designed for use in various applications, particularly in automotive environments where voltages can exceed the supply voltage.
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). The injection-current effect control is a key feature, allowing signals at disabled analog input channels to exceed the supply voltage without affecting the signal of the enabled analog channel.
