MM74C157 Quad 2-Input Multiplexers October 1987 Revised January 1999 MM74C157 Quad 2-Input Multiplexers General Description The MM74C157 multiplexers are monolithic plementary MOS (CMOS) integrated circuits constructed with Nand 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.
