1. General description

The 74HC157-Q100; 74HCT157-Q100 is a quad 2-input multiplexer. The device features select

(S) and enable E inputs. A HIGH on S selects data source 1, a LOW data source 0. A HIGH on E

forces all the outputs (1Y to 4Y) LOW. Inputs include clamp diodes. This enables the use of current

limiting resistors to interface inputs to voltages in excess of VCC.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
