Multiplexer selection for the 74AHC bus
The SN74AHC157DR is a 4-channel 2:1 multiplexer from Texas Instruments' 74AHC CMOS logic family, routing one of two 4-bit data sources to a common output based on the select input.
16-SOIC footprint and board integration
Housed in a 16-SOIC package (3.90mm body width, 0.154" pitch), the SN74AHC157DR mounts on the same land pattern as standard SOIC-16 logic devices. The surface-mount package suits automated assembly lines; the tape-and-reel option supports high-volume pick-and-place without reel changeovers.
