FUNCTION TABLE
Notes
1. H = HIGH voltage level
2. If the monostable was triggered before this condition
3. For this combination the reset input must be LOW and
nR
L = LOW voltage level
X = don’t care
was established the pulse will continue as
programmed.
the following sequence must be used:
pin 1 (or 9) must be set HIGH or pin 2 (or 10) set LOW;
then pin 1 (or 9) must be LOW and pin 2 (or 10) set
HIGH. Now the reset input goes from LOW-to-HIGH
and the device will be triggered.
