KK74ACT74

TECHNICAL DATA www.DataSheet4U.com KK74ACT74 Dual D Flip-Flop with Set and Reset High-Speed Silicon-Gate CMOS The KK74ACT74 is identical in pinout to the LS/ALS74, HC/HCT74. The KK74ACT74 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. This device consists of two D flip-flops with individual Set, Reset, and Clock inputs. Information at a D-input is transferred to the corresponding Q output on the next positive going edge of the clock input. Both Q and Q outputs are available from each flip-flop. The Set and Reset inputs are asynchronous. 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 µA; 0.1 µA @ 25°C Outputs Source/Sink 24 mA ORDERING INFORMATION KK74ACT74N Plastic KK74ACT74D SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Set L H L H H H H PIN 14 =VCC PIN 7 = GND Reset H L L H H H H L H Clock X X X Data X X X H L X X Outputs Q H L H * Q L H H* L H H L No Change No Change H H X No Change *Both outputs will remain high as long as Set and Reset are low, but the output states are unpredictable if Set and Reset go high simultaneously.
