TECHNICAL DATA
Dual D Flip-Flop with Set and Reset
High-Speed Silicon-Gate CMOS
IN74ACT74
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 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

*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.
