FUNCTION TABLE
Notes
1.
H = HIGH voltage level
L = LOW voltage level
X = don’t care
↑
= LOW-to-HIGH level
↓
= HIGH-to-LOW level
= one HIGH-level output pulse
= one LOW-level output pulse
If the monostable was triggered before this condition
was established the pulse will continue as
programmed.
For this combination the reset input must be LOW and
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.
