HD74HC78
Dual J-K Flip-Flops (with Preset, Common Clear and
Common Clock)
Description
This flip-flop is edge sensitive to the clock input and change state on the negative transition of the clock
pulse. Each flip-flop has independent J, K, and preset inputs and Q and
Q
outputs. Two flip-flops are
controlled by a common clear and a common clock. Preset and clear are independent of the clock and
accomplished by a low logic level on the corresponding input.
