96L02 DM96L02
Dual Retriggerable Resettable
Monostable Multivibrator
General Description
The 96L02 is a dual TTL monostable multivibrator with trig-
ger mode selection reset capability rapid recovery inter-
nally compensated reference levels and high speed capabil-
ity Output pulse duration and accuracy depend on external
timing components and are therefore under user control for
each application It is well suited for a broad variety of appli-
cations including pulse delay generators square wave gen-
erators long delay timers pulse absence detectors fre-
quency detectors clock pulse generators and fixed-frequen-
cy dividers Each input is provided with a clamp diode to
limit undershoot and minimize ringing induced by fast fall
times acting on system wiring impedances
Features
Y Retriggerable 0% to 100% duty cycle

Y Complementary outputs with active pull-ups
Y Pulse width compensation for DVCC and DTA
Y 50 ns to % output pulse width range
Y Optional retrigger lock-out capability
Y Resettable for interrupt operations
