Default Digital Monostable?

Hi,

1) Is there any equivalent to monostable in fully digital electronics
(logic gates)? I am trying to trigger a pulse (a set width) with a very
narrow recovery time (in the range of 100ns or less) before the next.
74LS221 seems to work although getting weird pulses (very short
retrigger pulses) occasionally.

2) And also whats the difference between the normal monostable and the
precision ones? As the name suggested they'd be more precise
triggering?

3) Would 74HCT version will be more suitable although I read somewhere
they are slower than the ls version.


Thanks,
John
