ESD224DQAR

Texas Instruments · ESD Protection Devices · USON-10(1x2.5)

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.
