TECHNICAL DATA
IN74HC253A
Dual 4-Input Data Selector/Multiplexer with 3-State Otputs
High-Performance Silicon-Gate CMOS
The IN74HC253A 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.
