The
KK
74AC74 is identical in pinout to the LS/ALS74, HC/HCT74.
The device inputs are compatible with standard CMOS outputs; with
pullup resistors, they are compatible with LS/ALS 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.
