put finger to keyboard and composed:

Just a suggestion, but wouldn't it be a whole hell of a lot simpler to just
use a 555 timer IC ? Just the chip, two Rs and one C (two Cs if you want to
be pedantic and decouple the control pin) to make a monostable which will
give utterly predictable results over a wide supply voltage and temperature
range, and has a very simple timing formula of approx 0.7CR.

Another option would be a 74LS123. Perhaps the OP's application
doesn't require precision, and perhaps he has a spare gate.
