High–Performance Silicon–Gate CMOS
The MC54/74HC74A 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

* 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.
