Manufacturer: National

Overview: MM54C157 MM74C157 Quad 2-Input Multiplexers February 1988 MM54C157 MM74C157 Quad 2-Input.

General Description

These multiplexers are monolithic plementary MOS (CMOS) integrated circuits constructed with N- and P-channel enhancement transistors They consist of four 2-input multiplexers with mon select and enable inputs When the enable input is at logical ‘‘0’’ the four outputs assume the values as selected from the inputs When the enable input is at logical ‘‘1’’ the outputs assume logical ‘‘0’’ Select decoding is done internally resulting in a single select input only
