MAX232EIPWR from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | C1+ | passive | Positive lead of C1 capacitor for the charge pump circuit. |
| 2 | VS+ | power_out | Positive charge pump output, nominally +8.5V, for external storage capacitor only. |
| 3 | C1- | passive | Negative lead of C1 capacitor for the charge pump circuit. |
| 4 | C2+ | passive | Positive lead of C2 capacitor for the charge pump circuit. |
| 5 | C2- | passive | Negative lead of C2 capacitor for the charge pump circuit. |
| 6 | VS- | power_out | Negative charge pump output, nominally -8.5V, for external storage capacitor only. |
| 7 | DOUT2 | output | RS-232 line data output for second driver (to remote RS-232 system); output voltage ±5V to ±7V. |
| 8 | RIN2 | input | RS-232 line data input for second receiver (from remote RS-232 system); accepts ±3V to ±30V input. |
| 9 | ROUT2 | output | Logic data output for second receiver (to UART); TTL/CMOS compatible, 0V to VCC. |
| 10 | DIN2 | input | Logic data input for second driver (from UART); TTL/CMOS compatible, accepts 0V to VCC. |
| 11 | DIN1 | input | Logic data input for first driver (from UART); TTL/CMOS compatible, accepts 0V to VCC. |
| 12 | ROUT1 | output | Logic data output for first receiver (to UART); TTL/CMOS compatible, 0V to VCC. |
| 13 | RIN1 | input | RS-232 line data input for first receiver (from remote RS-232 system); accepts ±3V to ±30V input. |
| 14 | DOUT1 | output | RS-232 line data output for first driver (to remote RS-232 system); output voltage ±5V to ±7V. |
| 15 | GND | power_in | Ground; 0V reference for all logic and power signals. |
| 16 | VCC | power_in | Supply voltage; connect to external 5V power supply between 4.5V and 5.5V. |
