IN74ACT74
IN74ACT74 is Dual D-Type Flip-Flop manufactured by IK Semiconductor.
TECHNICAL DATA
Dual D Flip-Flop with Set and Reset
High-Speed Silicon-Gate CMOS
The IN74ACT74 is identical in pinout to the LS/ALS74, HC/HCT74. The IN74ACT74 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 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 IN74ACT74N Plastic IN74ACT74D SOIC TA = -40° to 85° C for all packages
