Overview

SL74HC253 Dual 4-Input Data Selector/Multiplexer with 3-State Otputs High-Performance Silicon-Gate CMOS The SL74HC253 is identical in pinout to the LS/ALS253.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.
The Address Inputs select one of four Data Inputs from each multiplexer.
Each multiplexer has an active-low Output Enable control and a three-state noninverting output.
• Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2.
0 to 6.
0 V • Low Input Current: 1.
