## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | +Control | input | Anode of the channel 1 LED input; the LED is driven at about 1 mA to activate (1 mA max) and must stay within the 5 V maximum reverse input voltage. |
| 2 | -Control | input | Cathode of the channel 1 LED input; reverse input voltage is rated 5 V and reverse input current is 10 µA max at VR = 5 V. |
| 3 | +Control | input | Anode of the channel 2 LED input (polarity inferred, see review); the LED is driven at about 1 mA to activate and the reverse input voltage is rated 5 V. |
| 4 | -Control | input | Cathode of the channel 2 LED input (polarity inferred, see review); reverse input voltage is rated 5 V and reverse input current is 10 µA max at VR = 5 V. |
| 5 | Load | passive | Channel 2 MOSFET output terminal, rated for 60 VP blocking voltage and 120 mArms / mADC continuous load current, with on-resistance 16 Ω max at IL = 120 mA. |
| 6 | Load | passive | Channel 2 MOSFET output terminal, rated for 60 VP blocking voltage and 120 mArms / mADC continuous load current, with on-resistance 16 Ω max at IL = 120 mA. |
| 7 | Load | passive | Channel 1 MOSFET output terminal, rated for 60 VP blocking voltage and 120 mArms / mADC continuous load current, with on-resistance 16 Ω max at IL = 120 mA. |
| 8 | Load | passive | Channel 1 MOSFET output terminal, rated for 60 VP blocking voltage and 120 mArms / mADC continuous load current, with on-resistance 16 Ω max at IL = 120 mA. |
