MM74C157N

Revised May 2002 MM74C157 Quad 2-Input Multiplexers General Description Features The MM74C157 multiplexers are monolithic complementary MOS (CMOS) integrated circuits constructed with Nand 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 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. ■ Supply voltage range: 3V to 15V ■ High noise immunity: 0.45 VCC (typ.) ■ Low power: 50 nW (typ.) ■ Tenth power TTL compatible: Drive 2 LPTTL loads Ordering Code: Order Number MM74C157N Package Number N16E Package Description 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Connection Diagram Logic Diagram Top View Truth Table Enable Select A B Output Y 1 X X X 0 0 0 0 X 0 0 0 1 X 1 0 1 X 0 0 0 1 X 1 1 © 2002 Fairchild Semiconductor Corporation DS005894 www.fairchildsemi.com MM74C157 Quad 2-Input Multiplexers October 1987 MM74C157 Absolute Maximum Ratings(Note 1) Voltage at Any Pin −0.3V to VCC + 0.3V Operating Temperature Range −55°C to +125°C Storage Temperature Range −65°C to +150°C Maximum VCC Voltage 18V Power Dissipation (PD) Dual-In-Line 700 mW Small Outline 500 mW Operating VCC Range Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed.
