com KK74ACT253 Dual 4-Input Data Selector/Multiplexer with 3-State Otputs High-Speed Silicon-Gate CMOS The KK74ACT253 is identical in pinout to the LS/ALS253, HC/HCT253.
The KK74ACT253 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.
