SN65C3232DR from Texas Instruments, in a SOIC-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 charge-pump capacitor; connect the external 0.1 µF capacitor between C1+ and C1-. |
| 2 | V+ | power_out | Positive charge-pump output for the storage capacitor only; it is not intended as a load supply. |
| 3 | C1− | passive | Negative lead of the C1 charge-pump capacitor. |
| 4 | C2+ | passive | Positive lead of the C2 charge-pump capacitor. |
| 5 | C2− | passive | Negative lead of the C2 charge-pump capacitor. |
| 6 | V− | power_out | Negative charge-pump output for the storage capacitor only; it is not intended as a load supply. |
| 7 | DOUT2 | output | RS-232 line data output to the remote RS-232 system. |
| 8 | RIN2 | input | RS-232 line data input from the remote RS-232 system; receiver input range is -25 V to 25 V. |
| 9 | ROUT2 | output | Logic data output to the UART. |
| 10 | DIN2 | input | Logic data input from the UART; driver input range is 0 V to 5.5 V. |
| 11 | DIN1 | input | Logic data input from the UART; driver input range is 0 V to 5.5 V. |
| 12 | ROUT1 | output | Logic data output to the UART. |
| 13 | RIN1 | input | RS-232 line data input from the remote RS-232 system; receiver input range is -25 V to 25 V. |
| 14 | DOUT1 | output | RS-232 line data output to the remote RS-232 system. |
| 15 | GND | power_in | Ground reference for the device. |
| 16 | VCC | power_in | Supply voltage; connect to an external 3-V to 5.5-V power supply. |
