The KK74ACT112 is identical in pinout to the LS/ALS112, HC/HCT112. The KK74ACT112 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. Each flip-flop is negative-edge clocked and has active-low asynchronous Set and Reset inputs. 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 A; 0.1 A @ 25C Outputs Source/Sink 24 mA
