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
CMOS, NMOS, and TTL Operating
Voltage Range: 2.0 to 6.0 V Low Input Current: 1.0 µA High Noise Immunity Characteristic of
CMOS Devices
