DM96S02

Dual Retriggerable Resettable Monostable Multivibrator

General Description

The DM96S02 is a dual retriggerable and resettable

monostable multivibrator. This 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 2.0

M

Ω for the DM96S02 reduce required capacitor values.

Hysteresis is provided on the positive trigger input of the

DM96S02 for increased noise immunity.

Order Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
