BIS48510HW from BORN, in a SOIC-16-300mil. 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 | VDDA | power_in | Logic side power supply input; connect 0.1μF and 1μF bypass capacitors between VDDA and GNDA pins, placed as close as possible to the device. |
| 2 | GNDA | power_in | Logic side ground reference for digital signals. |
| 3 | RO | output | Receiver data output; when RE is low (enabled), outputs high if (VA-VB)>-50mV or low if (VA-VB)<-200mV, high-impedance when RE is high. |
| 4 | RE | input | Receiver enable control input, active low. |
| 5 | DE | input | Driver enable control input, active high; disables data transmission and sets driver output to high-impedance when low; enables driver when high. |
| 6 | DI | input | Driver data input; when DE is high, non-inverting output (A) follows DI logic level and inverting output (B) inverts DI level. |
| 7 | GNDA | power_in | Logic side ground reference for digital signals. |
| 8 | GNDA | power_in | Logic side ground reference for digital signals. |
| 9 | GNDB | power_in | Bus side ground reference for RS-485 bus signals. |
| 10 | GNDB | power_in | Bus side ground reference for RS-485 bus signals. |
| 11 | NC | unconnected | No internal connection. |
| 12 | A | bidirectional | RS-485 bus driver non-inverting output and receiver non-inverting input for half-duplex operation. |
| 13 | B | bidirectional | RS-485 bus driver inverting output and receiver inverting input for half-duplex operation. |
| 14 | NC | unconnected | No internal connection. |
| 15 | GNDB | power_in | Bus side ground reference for RS-485 bus signals. |
| 16 | VDDB | power_in | Bus side power supply input; connect 0.1μF and 1μF bypass capacitors between VDDB and GNDB pins, placed as close as possible to the device. |
