Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | C1+ | passive | Positive terminal of the 0.1µF flying capacitor C1 used by the +5V-to-+10V voltage doubler. |
| 2 | V+ | power_out | Charge-pump output that stores approximately +10V on the V+ filter capacitor, and a small amount of power may be drawn from it at the cost of reduced noise margin. |
| 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 +10V-to-−10V voltage inverter. |
| 5 | C2- | passive | Negative terminal of the 0.1µF flying capacitor C2 used by the voltage inverter. |
| 6 | V- | power_out | Charge-pump output that stores approximately −10V on the V- filter capacitor, and a small amount of power may be drawn from it at the cost of reduced noise margin. |
| 7 | T2OUT | output | RS-232 driver 2 output that swings ±5V minimum into a 3kΩ load per EIA/TIA-232E, with ±60mA typical short-circuit current and continuous short-circuit duration allowed. |
| 8 | R2IN | input | RS-232 receiver 2 input with about 5kΩ input resistance to ground, rated for ±30V input voltage and +0.8V/+2.4V thresholds. |
| 9 | R2OUT | output | CMOS receiver 2 output that is inverting relative to R2IN, and sits at logic 1 when the input is shorted to ground or left open. |
| 10 | T2IN | input | TTL/CMOS driver 2 input with an internal 400kΩ pullup to VCC, so unused inputs can be left open and should be driven high or open in shutdown to minimize supply current. |
| 11 | T1IN | input | TTL/CMOS driver 1 input with an internal 400kΩ pullup to VCC, so unused inputs can be left open and should be driven high or open in shutdown to minimize supply current. |
| 12 | R1OUT | output | CMOS receiver 1 output that is inverting relative to R1IN. |
| 13 | R1IN | input | RS-232 receiver 1 input with about 5kΩ input resistance to ground, rated for ±30V input voltage and +0.8V/+2.4V thresholds. |
| 14 | T1OUT | output | RS-232 driver 1 output that swings ±5V minimum into a 3kΩ load per EIA/TIA-232E, with ±60mA typical short-circuit current and continuous short-circuit duration allowed. |
| 15 | GND | power_in | Ground reference for the device and the RS-232 signal levels. |
| 16 | VCC | power_in | +5V supply input, specified at VCC = +5V ±10% for the MAX202. |
