Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | C1+ | passive | Positive terminal of the voltage-doubler charge-pump capacitor C1, which is 0.1µF for the MAX232A in the Figure 5 circuit. |
| 2 | V+ | power_out | Doubled charge-pump output at about +10V unloaded; it is unregulated, so it drops with load and must not be loaded below the minimum ±5V RS-232 driver level. |
| 3 | C1- | passive | Negative terminal of the voltage-doubler charge-pump capacitor C1. |
| 4 | C2+ | passive | Positive terminal of the voltage-inverter charge-pump capacitor C2. |
| 5 | C2- | passive | Negative terminal of the voltage-inverter charge-pump capacitor C2. |
| 6 | V- | power_out | Inverted charge-pump output at about -10V unloaded; it is unregulated, so it drops with load and must not be loaded below the minimum ±5V RS-232 driver level. |
| 7 | T2OUT | output | RS-232 driver 2 output, typically ±8V with a 5kΩ load at VCC = +5V, guaranteed to meet ±5V minimum and capable of being driven to ±15V. |
| 8 | R2IN | input | RS-232 receiver 2 input, which withstands ±30V overvoltage on the MAX232A family and has an internal 5kΩ terminating resistor. |
| 9 | R2OUT | output | TTL/CMOS output of receiver 2, which inverts the RS-232 input signal. |
| 10 | T2IN | input | TTL/CMOS input of driver 2, with a built-in 400kΩ pull-up to VCC so an unused driver input can be left unconnected. |
| 11 | T1IN | input | TTL/CMOS input of driver 1, with a built-in 400kΩ pull-up to VCC so an unused driver input can be left unconnected. |
| 12 | R1OUT | output | TTL/CMOS output of receiver 1, which inverts the RS-232 input signal. |
| 13 | R1IN | input | RS-232 receiver 1 input, which withstands ±30V overvoltage on the MAX232A family and has an internal 5kΩ terminating resistor. |
| 14 | T1OUT | output | RS-232 driver 1 output, typically ±8V with a 5kΩ load at VCC = +5V, guaranteed to meet ±5V minimum and capable of being driven to ±15V. |
| 15 | GND | power_in | Ground reference for the device. |
| 16 | VCC | power_in | +5V supply (±10% per the electrical characteristics), to be decoupled to GND close to the device in noise-sensitive applications. |
