74HC74
Dual D Flip−Flop with Set
and Reset
HighPerformance SiliconGate CMOS
The 74HC74 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 flipflops with individual Set, Reset,
and Clock inputs. Information at a Dinput 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 flipflop. The Set
and Reset inputs are asynchronous.
Features
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 mA
High Noise Immunity Characteristic of CMOS Devices
In Compliance with the JEDEC Standard No. 7A Requirements
ESD Performance: HBM > 2000 V; Machine Model > 200 V
Chip Complexity: 128 FETs or 32 Equivalent Gates
