74HC74
Dual D Flip−Flop with Set
and Reset
High−Performance Silicon−Gate 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 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.
