High-Performance Silicon-Gate CMOS
The MC574HC74A 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 Qbar outputs are available from each flip-flop. The Set and Reset inputs are asynchronous.
