H = HIGH voltage level;
L = LOW voltage level;
X = don’t care;
↑ = LOW-to-HIGH transition;
↓ = HIGH-to-LOW transition;
If the monostable multivibrator was triggered before this condition was established, the pulse will continue as programmed.
The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
For DIP16 packages: above 70 °C the value of P
For SO16 packages: above 70 °C the value of P
For SSOP16 and TSSOP16 packages: above 60 °C the value of P
For DHVQFN16 packages: above 60 °C the value of P
= one HIGH level output pulse;
= one LOW level output pulse.
