Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | C1+ | passive | Positive terminal for the charge-pump C1 capacitor, which sits between C1+ and C1-. |
| 2 | V+ | power_out | Positive voltage generated by the internal charge pump to supply the RS-232 driver high level. |
| 3 | C1- | passive | Negative terminal for the charge-pump C1 capacitor, which sits between C1+ and C1-. |
| 4 | C2+ | passive | Positive terminal for the charge-pump C2 capacitor, which sits between C2+ and C2-. |
| 5 | C2- | passive | Negative terminal for the charge-pump C2 capacitor, which sits between C2+ and C2-. |
| 6 | V- | power_out | Negative voltage generated by the internal charge pump to supply the RS-232 driver low level; the absolute maximum table gives a V- limit of -14 V. |
| 7 | T2OUT | output | RS-232 driver output at RS-232 levels; the transmitter output is limited to between V- minus 0.3 V and V+ plus 0.3 V per the absolute maximum ratings. |
| 8 | R2IN | input | RS-232 receiver input at RS-232 levels, rated for receiver input voltage of -30 V to 30 V. |
| 9 | R2OUT | output | RS-232 receiver output at TTL/CMOS levels, limited to -0.3 V to VCC plus 0.3 V. |
| 10 | T2IN | input | RS-232 driver input at TTL/CMOS levels, with transmitter input voltage of 0 V to VCC. |
| 11 | T1IN | input | RS-232 driver input at TTL/CMOS levels, with transmitter input voltage of 0 V to VCC. |
| 12 | R1OUT | output | RS-232 receiver output at TTL/CMOS levels, limited to -0.3 V to VCC plus 0.3 V. |
| 13 | R1IN | input | RS-232 receiver input at RS-232 levels, rated for receiver input voltage of -30 V to 30 V. |
| 14 | T1OUT | output | RS-232 driver output at RS-232 levels; the transmitter output is limited to between V- minus 0.3 V and V+ plus 0.3 V per the absolute maximum ratings. |
| 15 | GND | power_in | Ground reference for the device. |
| 16 | VCC | power_in | Supply voltage input; the features list 2.0 V to 6.0 V and the absolute maximum rating is 6.0 V. |
