Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | C1+ | passive | Terminal for the positive side of the charge-pump C1 capacitor (1.0 µF external capacitor in the typical application circuit). |
| 2 | V+ | power_out | Positive voltage generated by the charge pump; the datasheet limits the transmitter high output voltage V+ to a maximum of 9.8 V. |
| 3 | C1- | passive | Terminal for the negative side of the charge-pump C1 capacitor (1.0 µF external capacitor in the typical application circuit). |
| 4 | C2+ | passive | Terminal for the positive side of the charge-pump C2 capacitor (1.0 µF external capacitor in the typical application circuit). |
| 5 | C2- | passive | Terminal for the negative side of the charge-pump C2 capacitor (1.0 µF external capacitor in the typical application circuit). |
| 6 | V- | power_out | Negative voltage generated by the charge pump; the datasheet gives the transmitter low output voltage V- as -9.0 V minimum and 0.3 V maximum. |
| 7 | T2OUT | output | RS-232 driver output; the datasheet specifies a short-circuit output current of ±60 mA maximum. |
| 8 | R2IN | input | RS-232 receiver input; the datasheet specifies a receiver input voltage range of -20 V to 20 V. |
| 9 | R2OUT | output | RS-232 receiver output at TTL/CMOS levels; the voltage applied to the receiver output is limited to -0.3 V to VCC+0.3 V. |
| 10 | T2IN | input | RS-232 driver input at TTL/CMOS levels; the transmitter input voltage range is 0 V to VCC. |
| 11 | T1IN | input | RS-232 driver input at TTL/CMOS levels; the transmitter input voltage range is 0 V to VCC. |
| 12 | R1OUT | output | RS-232 receiver output at TTL/CMOS levels; the voltage applied to the receiver output is limited to -0.3 V to VCC+0.3 V. |
| 13 | R1IN | input | RS-232 receiver input; the datasheet specifies a receiver input voltage range of -20 V to 20 V. |
| 14 | T1OUT | output | RS-232 driver output; the datasheet specifies a short-circuit output current of ±60 mA maximum. |
| 15 | GND | power_in | Ground reference for the device. |
| 16 | VCC | power_in | Supply voltage input; the recommended operating range is 4.5 V to 5.5 V, with an absolute maximum of 6.0 V. |
