The MM74C157 multiplexers are monolithic complementary MOS (CMOS) integrated circuits constructed with Nand P-channel enhancement transistors. MM74C157 consist of four 2-input multiplexers with common 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 of MM74C157 is done internally resulting in a single select input only.
