TECHNICAL DATA

KK74AC253

Dual 4-Input Data Selector/Multiplexer

with 3-State Otputs

High-Speed Silicon-Gate CMOS

The KK74AC253 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 Directly Interface to CMOS, NMOS, and TTL

Operating Voltage Range: 2.0 to 6.0 V

Low Input Current: 1.0 µA; 0.1 µA @ 25°C

High Noise Immunity Characteristic of CMOS Devices

Outputs Source/Sink 24 mA
