Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | C1+ | passive | Positive terminal of the 0.1µF flying capacitor C1 that the voltage doubler uses to generate V+ from VCC. |
| 2 | V+ | power_out | Doubler output that stores approximately +10V on the V+ output filter capacitor (C3) and supplies the RS-232 driver positive swing. |
| 3 | C1- | passive | Negative terminal of the 0.1µF flying capacitor C1 used by the voltage doubler. |
| 4 | C2+ | passive | Positive terminal of the 0.1µF flying capacitor C2 used by the voltage inverter that generates V- from V+. |
| 5 | C2- | passive | Negative terminal of the 0.1µF flying capacitor C2 used by the voltage inverter. |
| 6 | V- | power_out | Inverter output that stores approximately -10V on the V- output filter capacitor (C4) and supplies the RS-232 driver negative swing. |
| 7 | T2OUT | output | RS-232 driver 2 output that gives at least ±5V into a 3kΩ load under worst-case conditions (typical ±8V with a 5kΩ receiver and VCC = +5V). |
| 8 | R2IN | input | RS-232 receiver 2 input rated for ±30V, with +0.8V/+2.4V thresholds, about 0.5V hysteresis, and about 5kΩ input resistance to ground. |
| 9 | R2OUT | output | TTL/CMOS receiver 2 output (inverting), specified at 0.4V maximum low at 3.2mA and 3.5V minimum high at 1.0mA. |
| 10 | T2IN | input | TTL/CMOS driver 2 input with 0.8V maximum low and 2.0V minimum high thresholds and an internal 400kΩ pullup to VCC, so an open input drives the output low. |
| 11 | T1IN | input | TTL/CMOS driver 1 input with 0.8V maximum low and 2.0V minimum high thresholds and an internal 400kΩ pullup to VCC, so an open input drives the output low. |
| 12 | R1OUT | output | TTL/CMOS receiver 1 output (inverting), specified at 0.4V maximum low at 3.2mA and 3.5V minimum high at 1.0mA. |
| 13 | R1IN | input | RS-232 receiver 1 input rated for ±30V, with +0.8V/+2.4V thresholds, about 0.5V hysteresis, and about 5kΩ input resistance to ground. |
| 14 | T1OUT | output | RS-232 driver 1 output that gives at least ±5V into a 3kΩ load under worst-case conditions (typical ±8V with a 5kΩ receiver and VCC = +5V). |
| 15 | GND | power_in | Ground reference for the device, the charge pump, and the RS-232 signals. |
| 16 | VCC | power_in | Single +5V supply input (VCC = +5V ±10% for MAX202), drawing a typical 8mA and a maximum 15mA with no load. |
