BL8023C from BL Shanghai Belling, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OA | output | Output A, relay driver output capable of 300mA typical driving current, logic state determined by inputs A and B according to logic function table. |
| 2 | NC | unconnected | Not connected to internal circuit. |
| 3 | A | input | Input A, active high with 3V threshold, input rise/fall time must be less than 1ms to prevent device damage. |
| 4 | GND | power_in | Ground, reference potential for device operation. |
| 5 | OB | output | Output B, relay driver output capable of 300mA typical driving current, logic state inverted relative to output A. |
| 6 | NC | unconnected | Not connected to internal circuit. |
| 7 | B | input | Input B, active high with 3V threshold, input rise/fall time must be less than 1ms to prevent device damage. |
| 8 | VIN | power_in | Supply voltage input, 5V to 36V operating range recommended, 40V absolute maximum, quiescent current 1μA typical. |
