The IR2181S is packaged in an 8-pin surface mount small outline integrated circuit (SOIC) package.

The IR2181S is a high voltage, high-speed power MOSFET and IGBT driver with independent high and low side referenced output channels. It typically has an 8-pin configuration in an SOIC-8 package. Here is a brief description of each pin's function:
1. VCC: Supply voltage for the lower gate drive bias.
2. IN: Input signal for the gate driver.
3. COM: Common ground reference for the low-side circuitry.
4. LO: Low-side gate drive output.
5. VS: High-side floating supply return, usually connected to the source of the high-side MOSFET or IGBT.
6. HO: High-side gate drive output.
7. VB: High-side floating gate drive supply voltage.
8. NC: No connection or internally not connected (depending on the version).
These pins allow the IR2181S to effectively drive both upper and lower power transistors in half-bridge or full-bridge configurations, which are commonly used in motor drives, power supplies, and other power electronics applications.
