October 1987 Revised May 2002 MM74C157 Quad 2-Input Multiplexers General Description The MM74C157 multiplexers are monolithic complemen- tary MOS (CMOS) integrated circuits constructed with N- and P-channel enhancement transistors. They consist of four 2-input multiplexers with common select and enable inputs. When the enable input is at logical “0” the four out- puts 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. Features s Supply voltage range: 3V to 15V s High noise immunity: 0.45 VCC (typ.) s Low power: 50 nW (typ.) s Tenth power TTL compatible: Drive 2 LPTTL loads Ordering Code: Order Number Package Number Package Description MM74C157N N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Connection Diagram Logic Diagram Top View Truth Table Enable 1 0 0 0 0 Select X 0 0 1 1 A B Output Y XX 0 0X 0 1X 1 X0 0 X1 1 © 2002 Fairchild Semiconductor Corporation DS005894 www.fairchildsemi.com Free Da 1 page
