Overview

MM54C157 MM74C157 Quad 2-Input Multiplexers February 1988 MM54C157 MM74C157 Quad 2-Input Multiplexers General Description These multiplexers are monolithic complementary 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 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 Features Y Y Y Y Supply voltage range High noise immunity Low power Tenth power TTL compatible 3V to 15V 0 45 VCC (typ ) 50 nW (typ ) Drive 2 LPTTL loads Logic Connection Diagrams Dual-In-Line Package TL F 5894 – 2 Top View Order Number MM54C157 or MM74C157 TL F 5894 – 1 Truth Table Enable 1 0 0 0 0 Select X 0 0 1 1 A X 0 1 X X B X X X 0 1 Output Y 0 0 1 0 1 Guaranteed Noise Margin as a Function of VCC 74L Compatibility TL F 5894 – 4 TL F 5894 – 3 C1995 National Semiconductor Corporation TL F 5894 RRD-B30M105 Printed in U S A Absolute Maximum Ratings (Note 1) If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Voltage at Any Pin Operating Temperature Range MM54C157 MM74C157 b 0 3V to VCC a 0 3V b 55 C to a 125 C b 40 C to a 85 C Storage Temperature Range Maximum VCC Voltage Power Dissipation (PD) Dual-In-Line Small Outline Operating VCC Range Lead Temperature (Soldering 10 sec ) b 65 C to a 150 C 18V 700 mW 500 mW 3V to 15V 260 C DC Electrical Characteristics Min Symbol CMOS TO CMOS VIN(1) VIN(0) VOUT(1) VOUT(0) IIN(1) IIN(0) ICC Logical ‘‘1’’ Input Voltage Logical ‘‘0’’ Input Voltage Logical ‘‘1’’ Output Voltage Logical ‘‘0’’ Output Voltage Logical ‘‘1’’ Input Current Logical ‘‘0’’ Input Current Supply Current Parameter Max limits apply across temperature ra...
