IN74ACT253
DUAL 4-INPUT DATA SELECTOR/MULTIPLEXER
WITH 3-STATE OTPUTS
High-Speed Silicon-Gate CMOS
The IN74ACT253 is identical in pinout to the LS/ALS253,
HC/HCT253. The IN74ACT253 may be used as a level converter
for interfacing TTL or NMOS outputs to High Speed CMOS
inputs.
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.
• TTL/NMOS Compatible Input Levels
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 4.5 to 5.5 V
• Low Input Current: 1.0 µA; 0.1 µA @ 25°C
• Outputs Source/Sink 24 mA
