Description
Manufacturer
IK Semiconductor
Datasheet
Dual D Flip-Flop with Set and Reset
are compatible with standard CMOS outputs; with pullup resistors, they are
compatible with LS/ALSTTL outputs.
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.
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0 µA
• High Noise Immunity Characteristic of CMOS Devices
The IN74HC74A is identical in pinout to the LS/ALS74. The device inputs
This device consists of two D flip-flops with individual Set, Reset, and

*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.
