HC253 Dual 4-Input Data Selector/Multiplexer with 3-State Otputs

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 CMO.
