The
KK
74HC74A is identical in pinout to the LS/ALS74. The device inputs
are compatible with standard CMOS outputs; with pullup resistors, they are
compatible with LS/ALSTTL 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.
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2.0 to 6.0 V
Low Input Current: 1.0

*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.
