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.
Outputs Directl
