Don't know what kind of timing requirement you need, but if you can't find anything premade, maybe you can try something like this-

Using a larger cap and resistor gives a longer output pulse, so you'd have to monkey around with the values to see what might work.

The second pulse gets generated when the incoming pulse goes low, so you'd have to see if the timing is suitable for your purposes.
