96L02 DM96L02 Dual Retriggerable Resettable Monostable Multivibrator
General Description
The 96L02 is a dual TTL monostable multivibrator with trigger mode selection reset capability rapid recovery internally compensated reference levels and high speed capability 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 applications including pulse delay generators square wave generators long delay timers pulse absence detectors frequency detectors clock pulse generators and fixed-frequency 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
