IN74AC253 Datasheet (IK Semiconductor) - Dual 4-1 Data Selector/Multiplexer

IN74AC253, Dual 4-1 Data Selector/Multiplexer

TECHNICAL DATA IN74AC253 Dual 4-Input Data Selector/Multiplexer with 3-State Otputs High-Speed Silicon-Gate CMOS The IN74AC253 is identical in pinout to the LS/ALS253, HC/HCT253.

The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS 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.
