CA-IS3080WX

Chipanalog · Isolated RS-485/422 Transceivers · SOIC-16-300mil

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.
