NOTES: 1. A retriggerable one-shot multivibrator has an output pulse width that is extended one full time period (T) after application of the last
trigger pulse.
2. A nontriggerable one-shot multivibrator has a time period (T) referenced from the application of the first trigger pulse.

† _{Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and}
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltages are referenced to GND, unless otherwise specified.
2. The package thermal impedance is calculated in accordance with JESD 51-7.
