Working Principles

The M74HC123RM13TR is a dual retriggerable monostable multivibrator. It operates based on the principles of triggering and resetting to generate precise pulses or time delays. The device has independent trigger and reset inputs, allowing for flexible control over its operation.

When a trigger pulse is applied to the Trigger (TR) input, the output Q goes high for a duration determined by the external timing components connected to the Threshold (TH) and Control Voltage (CV) pins. The output remains high until a reset pulse is applied to the Clear (CLR) input or until the timing period elapses.

The M74HC123RM13TR can be retriggered during the timing period by applying another trigger pulse. This feature allows for extending the output pulse width or generating a new pulse before the previous one ends.
