SN74AHC157D

Signal Switches, Multiplexers, Decoders Overview

The SN74AHC157D is a quadruple 2-line to 1-line data selector/multiplexer from the Texas Instruments AHC logic family. It integrates four independent multiplexers in a single package, featuring a common select input and an enable input for each device. The component operates within a supply voltage range of 2 V to 5.5 V and supports surface-mount installation in a SOIC-16 package. It exhibits a propagation delay of 7.5 ns and functions reliably across an operating temperature range of -40°C to +125°C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the selected component matches the required operating temperature range and electrical specifications for the target application environment.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when multiple independent 2-to-1 signal paths are required within a compact footprint. The AHC series offers improved speed and lower power consumption compared to legacy HC logic families. Consider the SOIC-16 package for standard surface-mount assembly processes and verify compatibility with the system's voltage levels and switching frequency requirements.
