SN74AHCT157QPWRQ1

Signal Switches, Multiplexers, Decoders Overview

The SN74AHCT157QPWRQ1 is an automotive-grade quadruple 2-line to 1-line data selector/multiplexer designed for 4.5V to 5.5V VCC operation. It features TTL-compatible inputs and balanced CMOS push-pull outputs. The device includes a common strobe (G) input that forces all outputs low when high. It operates asynchronously, selecting a 4-bit word from two sources based on the A/B address input. Qualified under AEC-Q100 Grade 1 with an operating temperature range of -40°C to +125°C.
