MC74HC74A
Dual D Flip-Flop with Set
and Reset
High–Performance Silicon–Gate CMOS
The MC74HC74A is identical in pinout to the LS74. The device
inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LSTTL outputs.
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.
• Output Drive Capability: 10 LSTTL Loads
• 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
• In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
• Chip Complexity: 128 FETs or 32 Equivalent Gates

*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.
