Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | C1+ | passive | Positive terminal of the first charge-pump capacitor; the datasheet specifies 1 µF external capacitors for the charge pump (typical application uses 0.1 µF). |
| 2 | V+ | power_out | Doubled voltage output of the charge pump, nominally +5.5 V, with absolute maximum VCC-0.3 to +7 V and a storage capacitor (C3) to ground. |
| 3 | C1- | passive | Negative terminal of the first charge-pump capacitor; the datasheet specifies 1 µF external capacitors for the charge pump (typical application uses 0.1 µF). |
| 4 | C2+ | passive | Positive terminal of the second charge-pump capacitor; the datasheet specifies 1 µF external capacitors for the charge pump (typical application uses 0.1 µF). |
| 5 | C2- | passive | Negative terminal of the second charge-pump capacitor; the datasheet specifies 1 µF external capacitors for the charge pump (typical application uses 0.1 µF). |
| 6 | V- | power_out | Inverted voltage output of the charge pump, nominally -5.5 V, with absolute limit +0.3 to -7 V as printed in the limiting values table. |
| 7 | T2OUT | output | Second RS-232 transmitter output, swing typically ±5 V into a 3 kΩ load, with absolute maximum range ±13.2 V and short-circuit current 60 mA. |
| 8 | R2IN | input | Second RS-232 receiver input with a ±25 V input range and 3 kΩ to 7 kΩ input impedance. |
| 9 | R2OUT | output | Second CMOS receiver output with absolute range -0.3 V to VCC+0.3 V, logic-low at most 0.4 V at 1.6 mA and logic-high at least VCC-0.6 V at -0.5 mA. |
| 10 | T2IN | input | Second TTL/CMOS transmitter input with logic-low up to 0.8 V and logic-high from 2 V, no internal pull-up, and may be tied to GND or VCC if unused. |
| 11 | T1IN | input | First TTL/CMOS transmitter input with logic-low up to 0.8 V and logic-high from 2 V, no internal pull-up, and may be tied to GND or VCC if unused. |
| 12 | R1OUT | output | First CMOS receiver output with absolute range -0.3 V to VCC+0.3 V, logic-low at most 0.4 V at 1.6 mA and logic-high at least VCC-0.6 V at -0.5 mA. |
| 13 | R1IN | input | First RS-232 receiver input with a ±25 V input range and 3 kΩ to 7 kΩ input impedance. |
| 14 | T1OUT | output | First RS-232 transmitter output, swing typically ±5 V into a 3 kΩ load, with absolute maximum range ±13.2 V and short-circuit current 60 mA. |
| 15 | GND | power_in | Ground reference for all device voltages. |
| 16 | VCC | power_in | Supply voltage of 3 V to 5.5 V, with absolute maximum range -0.3 V to +6 V. |
