Table 4-1 Pin Functions
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| C1+ | 2 | — | Positive terminals of the voltage-doubler charge pump capacitors |
| C2+ | 5 | ||
| C1– | 4 | — | Negative terminals of the voltage-doubler charge pump capacitors |
| C2– | 6 | ||
| DIN | 11 | I | Driver input |
| DOUT | 13 | O | RS-232 driver output |
| EN | 1 | I | Low input enables receiver ROUT output. High input sets ROUT to high impedance. |
| FORCEOFF | 16 | I | Automatic power-down control input |
| FORCEON | 12 | I | Automatic power-down control input |
| GND | 14 | — | Ground |
| INVALID | 10 | O | Invalid output pin. Output low when RIN input is unpowered. |
| RIN | 8 | I | RS-232 receiver input |
| ROUT | 9 | O | Receiver output |
| VCC | 15 | — | 3V to 5.5V supply voltage |
| V+ | 3 | O | 5.5V supply generated by the charge pump |
| V– | 7 | O | –5.5V supply generated by the charge pump |
