DUAL RETRIGGERABLE MONOSTABLE MULTIVIBRATOR
WITH SCHMITT TRIGGER INPUTS

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description/ordering information (continued)
Once triggered, the basic pulse duration can be extended by retriggering the gated low-level-active (A) or
high-level-active (B) input. Pulse duration can be reduced by taking CLR low. The input/output timing diagram
illustrates pulse control by retriggering the inputs and early clearing.
During power up, Q outputs are in the low state, and Q outputs are in the high state. The outputs are glitch free,
without applying a reset pulse.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
