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 Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2.0 to 6.0 V
Low Input Current: 1.0
