positive edged triggered SR latch or flip-flop?

[danjel]

Is there a standard part that exists where the S and R inputs are edge triggered (not level).

Typically only the CLK input is edge triggered on flipflops.

I only want these inputs to trigger a change in the input when they transition.

The only way I can think of doing this is to use a gate to pulse converter on the source signals so that they are only ON for a short period of time.

You could apply the S/R pulse to the FF input through a series capacitor, with a resistor connected from the FF input to ground.

Yeah I think this is the simplest solution. Alternatively I found this:

It uses two D FlipFlops for each SR flipflop

What about a J/K?

You do want the flip-flop to trigger on just one edge (slope) of the signal or both edges?
