Functional Description
The 96S02 dual retriggerable resettable monostable multi-
vibrator has tow DC coupled trigger inputs per function,
one active LOW (I0) and one active HIGH (I1). The I1 input
utilizes an internal Schmitt trigger with hysteresis of 0.3V to
provide increased noise immunity. The use of active HIGH
and LOW inputs allows wither rising or falling edge trigger-
ing and optional non-retriggerable operation. The inputs
are DC coupled making triggering independent of input
transition times. When input conditions for triggering are
met the Q output goes HIGH and the external capacitor is
rapidly discharged and then allowed to recharge. An input

trigger which occurs during the timing cycle will retrigger
the circuit and result in Q remaining HIGH. The output
pulse may be terminated (Q to the LOW state) at any time
by setting the Direct Clear input LOW. Retriggering may be
inhibited by tying the Q output to I0 or the Q output to I1.
Differential sensing techniques are used to obtain excellent
stability over temperature and power supply variations and
a feedback Darlington capacitor discharge circuit mini-
mizes pulse width variation from unit to unit. Schottky TTL
output stages provide high switching speeds and output
compatibility with all TTL logic families.
