Overview
The 74HC157D-Q100,118 is a quad 2-input multiplexer produced by NXP USA Inc., now part of Nexperia. This device is designed to select one of two data sources based on the state of the select input (S). It features an enable input (E) that, when set high, forces all outputs to a low state. The 74HC157D-Q100,118 is fabricated using silicon gate C2MOS technology, which provides high-speed operation similar to LSTTL while maintaining the low power dissipation characteristic of CMOS devices.
This component is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for use in automotive applications. It operates over a wide temperature range from -40°C to +125°C and supports a supply voltage range of 2.0 V to 6.0 V.
