Dual D Flip−Flop with Set and Reset
High−Performance Silicon−Gate CMOS

The MC74HC74A 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.
