The KK74ACT175 is identical in pinout to the LS/ALS175, HC/HCT175. The KK74ACT175 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. This device consists of four D flip-flops with common Reset and Clock inputs, and separate D inputs. Reset (active-low) is asynchronous and occurs when a low level is applied to the Reset input. Information at a D input is transferred to the corresponding Q output on the next positivegoing edge of the Clock input. 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
