I want a flip flop to trigger between 1 and 0 each time it receives a 5V pulse (from a button pushed on a keypad.) Otherwise I want it to stay in its current state, even when the keypad is disconnected and the input floats. I was thinking of using a flipflop, with the input tied via a pull up/down (depending on state) resistor to its output. What sort of flip flop is best for this application?
Thank you
