KK74ACT273 Datasheet | Kodenshi AUK Group

TECHNICAL DATA .. Octal D Flip-Flop with mon Clock and Reset High-Speed Silicon-Gate CMOS The KK74ACT273 is identical in pinout to the LS/ALS273, HC/HCT273. The KK74ACT273 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. This device consists of eight D flip-flops with mon 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 patible 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; 0.1 µA @ 25°C - Outputs Source/Sink 24 m A ORDERING INFORMATION KK74ACT273N Plastic KK74ACT273DW SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Reset L PIN 20=VCC PIN 10 = GND H H H H X = don’t care L Clock X D X H L X X Output Q L H L no change no change ..
