IN74HC253A Datasheet (IK Semiconductor) - Dual 4-1 Data Selector/Multiplexer

IN74HC253A, Dual 4-1 Data Selector/Multiplexer

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.
