# Pulse Stretch Options

Case 1. Input pulse duration &lt; setting duration: stretch duration = setting time.
![0 Setting time\nInput pulse\nInput pulse](.hsl-di16-ul-datasheet-1/be1c851689566be2639ac3750bd619daba8a93d83bdb47fd989d3f8a1181773d.jpg)

Case 2. Input pulse duration &gt; setting duration: stretch duration = input pulse duration

Case 3. Input pulse duration < setting duration, but extra pulses occurs in this period: Stretch active based on first pulse.

Case 4. Input pulse duration < setting duration, but extra pulse occurs at the end of setting time: Stretch will extend the duration until extra pulse ends.
