MC74HC74A - Dual D Flip-Flop
MOTOROLA SEMICONDUCTOR TECHNICAL DATA Dual D Flip-Flop with Set and Reset 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 go
