CA-IS3080WX from Chipanalog, 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 (A) power supply. Operating range 2.375-5.5 V (recommended 2.5-5.5 V). |
| 2 | GNDA | power_in | Logic-side (A) ground reference. |
| 3 | RO | output | Receiver output. RO is high when A is at least 200 mV above B; RO is low when A is at least 200 mV below B. |
| 4 | /RE | input | Receiver enable, active low. RE low enables the receiver; RE high places the receiver output in high impedance. |
| 5 | DE | input | Driver enable, active high. DE high enables the driver; DE low places driver outputs in high impedance. With DE high the device is in transmit mode; with DE low and /RE low it is in receive mode. |
| 6 | DI | input | Driver data input. DI high drives A high and B low; DI low drives the opposite. |
| 7 | GNDA | power_in | Logic-side (A) ground reference. |
| 8 | GNDA | power_in | Logic-side (A) ground reference. |
| 9 | GNDB | power_in | Bus-side (B) ground reference. |
| 10 | GNDB | power_in | Bus-side (B) ground reference. |
| 11 | Y | output | Bus-side non-inverting driver output (RS-485 differential transmit +). |
| 12 | Z | output | Bus-side inverting driver output (RS-485 differential transmit -). |
| 13 | B | input | Bus-side inverting receiver input (RS-485 differential receive -). |
| 14 | A | input | Bus-side non-inverting receiver input (RS-485 differential receive +). |
| 15 | GNDB | power_in | Bus-side (B) ground reference. |
| 16 | VDDB | power_in | Bus-side (B) power supply. Recommended operating range 4.5-5.5 V. |
