Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | C1+ | passive | Positive terminal of the voltage doubler charge-pump capacitor; the external capacitors can be as low as 0.1µF with a 16V breakdown voltage rating. |
| 2 | V+ | power_out | +5.5V output generated by the charge pump, with a maximum magnitude of 7V (absolute maximum) and V+ + |
| 3 | C1- | passive | Negative terminal of the voltage doubler charge-pump capacitor. |
| 4 | C2+ | passive | Positive terminal of the inverting charge-pump capacitor. |
| 5 | C2- | passive | Negative terminal of the inverting charge-pump capacitor. |
| 6 | V- | power_out | -5.5V output generated by the charge pump, with a maximum magnitude of 7V (absolute maximum) and V+ + |
| 7 | T2OUT | output | RS-232 driver output that swings at least ±5V into a 3kΩ load and is protected against continuous short-circuit to ground. |
| 8 | R2IN | input | RS-232 receiver input with a -15V to +15V input voltage range, a typical 5kΩ pulldown to ground when unconnected, and an absolute maximum of ±25V. |
| 9 | R2OUT | output | TTL/CMOS receiver output that is HIGH at VCC -0.6V minimum (sourcing 1.0mA) and LOW at 0.4V maximum (sinking 1.6mA). |
| 10 | T2IN | input | TTL/CMOS driver input with logic LOW at 0.8V maximum and logic HIGH at 2.0V (VCC = 3.3V) or 2.4V (VCC = 5.0V) minimum; unused inputs should be tied to VCC or GND since there are no pull-up resistors. |
| 11 | T1IN | input | TTL/CMOS driver input with logic LOW at 0.8V maximum and logic HIGH at 2.0V (VCC = 3.3V) or 2.4V (VCC = 5.0V) minimum; unused inputs should be tied to VCC or GND since there are no pull-up resistors. |
| 12 | R1OUT | output | TTL/CMOS receiver output that is HIGH at VCC -0.6V minimum (sourcing 1.0mA) and LOW at 0.4V maximum (sinking 1.6mA). |
| 13 | R1IN | input | RS-232 receiver input with a -15V to +15V input voltage range, a typical 5kΩ pulldown to ground when unconnected, and an absolute maximum of ±25V. |
| 14 | T1OUT | output | RS-232 driver output that swings at least ±5V into a 3kΩ load and is protected against continuous short-circuit to ground. |
| 15 | GND | power_in | Ground reference for the device. |
| 16 | VCC | power_in | Supply voltage of +3.0V to +5.5V (absolute maximum -0.3V to +6.0V). |
