The
KK
74ACT253 is identical in pinout to the LS/ALS253,
HC/HCT253. The
KK
74ACT253 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
