Description
The CD54AC109/3A and CD54ACT109/3A are dual “J-K” flip-flops with set and reset that utilize the Harris Advanced CMOS Logic technology. These flip-flops have independent J, K, Set, Reset and Clock inputs and Q and Q outputs. The CD54AC109/3A and CD54ACT109/3A changes state on the positive-going transition of the clock. Set and Reset are accomplished asynchronously by low-level inputs.

The CD54AC109/3A and CD54ACT109/3A are supplied in 16 lead dual-in-line ceramic packages (F suffix).
