Hi, I'm new to this forum.
I need to replace a no more available T flip-flop BA634 with a 4013 into an existing circuit.
But there are some differences between these 2 ICs:
1 - the change of state must be on a descending front using a mechanical switch to ground (from +9v to 0).
2 - the output must drive 2 transistors and one led
3 - the reset must act on ground, then stay on +9v
I can't have an other IC on the circuit, but I think I will need a couple of transistors for inverting and for output power.
I may also use a HEF4013B instead of a regular 4013 to avoid switch bounce troubles, even if the actual circuit has a 47k pull-up resistor, and a 0.010 capacitor to ground.
Your advices?
