XL3232 from XINLUDA, in a SOP-16. 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 | C1+ | passive | Positive lead of the C1 capacitor for the internal charge pump, which requires four external capacitors of 0.1 µF. |
| 2 | V+ | power_out | Positive charge pump output for storage capacitor only; the datasheet specifies V+ absolute maximum of 7 V. |
| 3 | C1- | passive | Negative lead of the C1 capacitor for the internal charge pump. |
| 4 | C2+ | passive | Positive lead of the C2 capacitor for the internal charge pump. |
| 5 | C2- | passive | Negative lead of the C2 capacitor for the internal charge pump. |
| 6 | V- | power_out | Negative charge pump output for storage capacitor only; the datasheet specifies V- absolute maximum of -7 V. |
| 7 | DOUT2 | output | RS232 line driver output to the remote RS232 system; outputs are protected against shorts to ground. |
| 8 | RIN2 | input | RS232 line receiver input from the remote RS232 system, with an internal standard RS232 load; an open input gives a high ROUT output. |
| 9 | ROUT2 | output | Logic data output to the UART from the RS232 receiver. |
| 10 | DIN2 | input | Logic data input from the UART to the RS232 driver; all DIN inputs must be valid low or high logic levels. |
| 11 | DIN1 | input | Logic data input from the UART to the RS232 driver; all DIN inputs must be valid low or high logic levels. |
| 12 | ROUT1 | output | Logic data output to the UART from the RS232 receiver. |
| 13 | RIN1 | input | RS232 line receiver input from the remote RS232 system, with an internal standard RS232 load. |
| 14 | DOUT1 | output | RS232 line driver output to the remote RS232 system; outputs are protected against shorts to ground. |
| 15 | GND | power_in | Ground reference for the device. |
| 16 | VCC | power_in | Supply voltage, connect to external 3-V to 5.5-V power supply. |
