Reference families: Manufacturer

Produces a timed output pulse that can be extended by a qualifying retrigger condition.

## What it represents

Produces a timed output pulse that can be extended by a qualifying retrigger condition.
On a schematic, identify the trigger polarities, clear input and timing components and trace the pulse/complemented outputs and timed control use. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
A retriggerable one-shot differs from a non-retriggerable pulse generator or a free-running oscillator.
The preview is an independently drawn educational functional reference. Add the selected component’s actual power pins, terminal numbers, timing or analogue reference details when producing a construction drawing.

## How to read it

- Identify the trigger polarities, clear input and timing components.
- Trace the pulse/complemented outputs and timed control use.

## Information to show or reference

- Label the trigger polarities, clear input and timing components.
- Cross-reference the pulse/complemented outputs and timed control use.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.

## Important distinction

A retriggerable one-shot differs from a non-retriggerable pulse generator or a free-running oscillator.

## Facts

- Common schematic mnemonic: ONE-SHOT — descriptive only; project/device documentation defines reference designations.
- Terminal / interface focus: The trigger polarities, clear input and timing components
- Artwork scope: Original educational functional/circuit reference; not a selected product pinout.
