Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VR | input | Reference voltage input to differential amplifier with maximum pin currents of 250 µA (VR-IN) or 30 mA (VR-GND). |
| 2 | IN | input | Input signal from zero-current transformer with maximum pin currents of 250 µA (IN-VR) or 30 mA (IN-GND). |
| 3 | GND | power_in | Ground reference for the circuit. |
| 4 | OD | output | Differential amplifier output with typical currents of -12 to -30 µA at VOD=1.2V or 17 to 37 µA at VOD=0.8V. |
| 5 | SC | input | Latch circuit input with ON voltage range of 0.7 to 1.4V and typical input current of 5 µA. |
| 6 | NR | input | Noise suppression input pin, typically connected to capacitor network. |
| 7 | OS | output | Final logic output to SCR gate with output current of -100 µA at 25°C or -75 µA at 80°C (VOS=0.8V). |
| 8 | VS | power_in | Power supply voltage input with typical quiescent current of 400-580 µA at VS=12V and VR-Vi=30mV. |
