100371 Low Power Triple 4-Input Multiplexer with Enable General Description The 100371 contains three 4-input multiplexers which share a common decoder (inputs S0 and S1). Output buffer gates provide true and complement outputs. A HIGH on the Enable input (E) forces all true outputs LOW (see Truth Table). All inputs have 50 kΩ pull-down resistors. n n n n 2000V ESD protection Pin/function compatible with 100171 Voltage compensated operating range = −4.2V to −5.7V Available to MIL-STD-883 Features n 35% power reduction of the 100171 Logic Symbol Pin Names Description I0x–I3x Data Inputs S0, S1 Select Inputs E Enable Input (Active LOW) Za–Zc Data Outputs Za–Zc Complementary Data Outputs DS100975-1 © 1998 National Semiconductor Corporation DS100975 www.national.com 100371 Low Power Triple 4-Input Multiplexer with Enable September 1998 Connection Diagrams 24-Pin DIP DS100975-2 24-Pin Quad Cerpak DS100975-3 Logic Diagram DS100975-5 www.national.com 2 Truth Table Inputs Outputs E S0 S1 Zn L L L I0x L H L I1x L L H I2x L H H I3x H X X L H = HIGH Voltage Level L = LOW Voltage Level X = Don’t Care 3 www.national.com Absolute Maximum Ratings (Note 1) Recommended Operating Conditions If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications.
