Note :
1. The trigger functions only on the falling edge of the trigger pulse only after previously being high. After reset the trigger must
be brought high and then low to implement triggering.
2. For reset below 0.8V, outputs set low and trigger inhibited.
3. Output structure is open collector which requires a pull up resistor to V
CC
to sink current.
The output is normally low sinking current.
