ESD224DQAR 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_C | bidirectional | Connector-side ESD-protected I/O channel 1, to be connected to the HDMI connector and paired with system-side pin 10 (IO1_S). |
| 2 | IO2_C | bidirectional | Connector-side ESD-protected I/O channel 2, to be connected to the HDMI connector and paired with system-side pin 9 (IO2_S). |
| 3 | GND | power_in | Ground, to be connected to system ground; the GND pins (3 and 8) are shorted internally. |
| 4 | IO3_C | bidirectional | Connector-side ESD-protected I/O channel 3, to be connected to the HDMI connector and paired with system-side pin 7 (IO3_S). |
| 5 | IO4_C | bidirectional | Connector-side ESD-protected I/O channel 4, to be connected to the HDMI connector and paired with system-side pin 6 (IO4_S). |
| 6 | IO4_S | bidirectional | System-side I/O pin corresponding to IO4_C, to be connected to the system side. |
| 7 | IO3_S | bidirectional | System-side I/O pin corresponding to IO3_C, to be connected to the system side. |
| 8 | GND | power_in | Ground, to be connected to system ground; the GND pins (3 and 8) are shorted internally. |
| 9 | IO2_S | bidirectional | System-side I/O pin corresponding to IO2_C, to be connected to the system side. |
| 10 | IO1_S | bidirectional | System-side I/O pin corresponding to IO1_C, to be connected to the system side. |
