DM96LS02

Dual Retriggerable Resettable Monostable Multivibrator

General Description

The DM96LS02 is a dual retriggerable and resettable

monostable multivibrator. The one-shot provides excep-

tionally wide delay range, pulse width stability, predictable

accuracy and immunity to noise. The pulse width is set by

an external resistor and capacitor. Resistor values up to 1.0

M

Ω reduce required capacitor values. Hysteresis is pro-

vided on both trigger inputs of the DM96LS02 for increased

noise immunity.

Features

s Required timing capacitance reduced by factors of 10 to

100 over conventional designs

s Broad timing resistor range—1.0 k

Ω to 2.0 MΩ

s Output Pulse Width is variable over a 2000:1 range by

resistor control

s Propagation delay of 35 ns

s 0.3V hysteresis on trigger inputs

s Output pulse width independent of duty cycle

s 35 ns to

∞ output pulse width range
