The IN74ACT174 is identical in pinout to the LS/ALS174, HC/HCT174. The IN74ACT174 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. This device consists of six D flip-flops with common Clock and Reset inputs. Each flip-flop is loaded with a low-to-high transition of the Clock input. Reset is asynchronous and active-low. 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
