Aip54123 from Wuxi I-core Elec, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VR | passive | Reference voltage terminal; the ZCT and its load resistor RL connect between pins 1 and 2, with a ~0.047µF noise-removal capacitor to GND; absolute max current 30 mA to ground. |
| 2 | IN | input | Differential amplifier input terminal connected to the ZCT secondary; absolute max current 30 mA to ground. |
| 3 | GND | power_in | Ground. |
| 4 | OD | output | Op-amp differential output; an external capacitor to ground (0.047µF in the operating-time test) is used for noise removal. |
| 5 | SC | input | Latch input terminal with SC turn-on voltage of 0.7 V to 1.4 V and absolute max current of 5 mA. |
| 6 | NR | passive | Noise absorption terminal; a capacitor of about 0.047µF connects between pin 6 and pin 7. |
| 7 | OS | output | Output terminal; external capacitor COS to GND must be 1 µF max. |
| 8 | VS | power_in | Supply voltage terminal; at least 12 V is needed with the latch circuit off, with an external capacitor CVS to GND of 1 µF min. |
