ESD204DQAR from Texas Instruments, in a USON-10(1x2.5). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IO1 | bidirectional | Bidirectional ESD-protected signal I/O; clamps transients to ground with ±3.6 V operating range. |
| 2 | IO2 | bidirectional | Bidirectional ESD-protected signal I/O; clamps transients to ground with ±3.6 V operating range. |
| 3 | GND | power_in | Ground reference for ESD protection diode network. |
| 4 | IO3 | bidirectional | Bidirectional ESD-protected signal I/O; clamps transients to ground with ±3.6 V operating range. |
| 5 | IO4 | bidirectional | Bidirectional ESD-protected signal I/O; clamps transients to ground with ±3.6 V operating range. |
| 6 | NC | unconnected | Not internally connected; can be used for optional flow-through routing or left floating or grounded. |
| 7 | NC | unconnected | Not internally connected; can be used for optional flow-through routing or left floating or grounded. |
| 8 | GND | power_in | Ground reference for ESD protection diode network. |
| 9 | NC | unconnected | Not internally connected; can be used for optional flow-through routing or left floating or grounded. |
| 10 | NC | unconnected | Not internally connected; can be used for optional flow-through routing or left floating or grounded. |
