IN74ACT253
IN74ACT253 is Dual 4-1 Data Selector/Multiplexer manufactured by IK Semiconductor.
TECHNICAL DATA
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 patible 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 m A
