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).
