74AHC123A; 74AHCT123A
Dual retriggerable monostable multivibrator with reset
6. Functional description
[1] H = HIGH voltage level;
L = LOW voltage level;
X = don’t care;
= LOW-to-HIGH transition;
= HIGH-to-LOW transition;
= one HIGH level output pulse;
= one LOW level output pulse.
[2] If the monostable multivibrator was triggered before this condition was established, the pulse will continue as programmed.
7. Limiting values
[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] P
tot
derates linearly with 8 mW/K above 70 C.
[3] P
