4 x 2:1 multiplexer — what the 74AC logic family brings
The Texas Instruments CD74AC157M is a single-supply 4 x 2:1 multiplexer from the 74AC family. It selects one of two 4-bit data inputs and routes it to the output, controlled by a common select line. The 74AC series gives you the speed of advanced CMOS with the drive of 24 mA per output, enough to fan out to multiple loads without external buffers.
