Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | C1+ | passive | Positive terminal of charge-pump capacitor C1, which is 1.0µF for the MAX232 in the datasheet capacitor table. |
| 2 | V+ | power_out | Doubler charge-pump output at nominally +10V unloaded; it is not regulated and must not be loaded so far that the RS-232 driver output falls below the ±5V EIA/TIA-232E minimum. |
| 3 | C1- | passive | Negative terminal of charge-pump capacitor C1, which is 1.0µF for the MAX232 in the datasheet capacitor table. |
| 4 | C2+ | passive | Positive terminal of charge-pump capacitor C2, which is 1.0µF for the MAX232 in the datasheet capacitor table. |
| 5 | C2- | passive | Negative terminal of charge-pump capacitor C2, which is 1.0µF for the MAX232 in the datasheet capacitor table. |
| 6 | V- | power_out | Inverter charge-pump output at nominally -10V unloaded; it is not regulated and must not be loaded so far that the RS-232 driver output falls below the ±5V EIA/TIA-232E minimum. |
| 7 | T2OUT | output | RS-232 driver 2 output, typically ±8V with a 5kΩ load and VCC = +5V, guaranteed to ±5V minimum with a 3kΩ load, and can be driven to ±15V. |
| 8 | R2IN | input | RS-232 receiver 2 input with an internal nominal 5kΩ terminating resistor, withstanding input voltages up to ±30V on devices other than the MAX220. |
| 9 | R2OUT | output | TTL/CMOS receiver 2 output; the receiver inverts, and the output is limited to -0.3V to (VCC + 0.3V). |
| 10 | T2IN | input | TTL/CMOS-compatible driver 2 input with a built-in 400kΩ pullup to VCC; leave unused driver inputs unconnected or tie them high, since the pullup forces the unused driver output low. |
| 11 | T1IN | input | TTL/CMOS-compatible driver 1 input with a built-in 400kΩ pullup to VCC; leave unused driver inputs unconnected or tie them high, since the pullup forces the unused driver output low. |
| 12 | R1OUT | output | TTL/CMOS receiver 1 output; the receiver inverts, and the output is limited to -0.3V to (VCC + 0.3V). |
| 13 | R1IN | input | RS-232 receiver 1 input with an internal nominal 5kΩ terminating resistor, withstanding input voltages up to ±30V on devices other than the MAX220. |
| 14 | T1OUT | output | RS-232 driver 1 output, typically ±8V with a 5kΩ load and VCC = +5V, guaranteed to ±5V minimum with a 3kΩ load, and can be driven to ±15V. |
| 15 | GND | power_in | Ground reference (0V) for all device voltages. |
| 16 | VCC | power_in | Supply input at +5V ±10% per the electrical characteristics, with absolute maximum rating of -0.3V to +6V. |
