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.

Note 2. For reset below 0.8V, outputs set low and trigger inhibited. For reset above 2.4V, trigger

enabled.

Note 3. The NTE926 output structure is open–collector which requires a pull–up resistor to VCC to

sink current. The output is normally low sinking current.
