CA-IS3092VW

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

CA-IS3092VW from Chipanalog, in a SOIC-16-300mil. 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 VCC power_in Logic-side supply that powers the internal DC-DC converter and, on the VW version, is decoupled with 0.1 µF and 10 µF capacitors placed within 2 mm of the pin; recommended range 3.15 V to 5.5 V.
2 GNDA power_in Logic-side ground and the reference point for logic-side signals (also pin 8).
3 RO output Receiver data output, which goes high-impedance when the receiver is disabled (RE high), per truth table 9-1.
4 RE input Active-low receiver enable: low enables the receiver, high disables it and puts RO in high-impedance, and it is weakly pulled up internally to VCCL on the VW version.
5 DE input Active-high driver enable: high enables the driver, low puts the driver outputs in high-impedance, and it is weakly pulled down internally to GNDA.
6 DI input Driver data input: with DE high, DI high drives A high and B low, and DI low drives A low and B high; it is weakly pulled up internally to VCCL on the VW version.
7 VCCL power_in Logic-side RS-485 supply that sets the logic input thresholds and output levels on the VW version, with a recommended range of 2.375 V to 5.5 V and a 1 µF bypass capacitor to GNDA.
8 GNDA power_in Logic-side ground and the reference point for logic-side signals (also pin 2).
9 GNDB power_in Bus-side ground and the reference point for the RS-485 bus signals (also pin 15).
10 SEL input VISO output voltage select: tie to VISO for 5 V output, or tie to GNDB or leave floating for 3.3 V output, and it must be set before start-up and not changed during start-up (with VCC at 3.3 V, SEL must be GNDB or floating).
11 NC unconnected No internal connection on the VW version.
12 A bidirectional RS-485 bus non-inverting receiver input and driver non-inverting output.
13 B bidirectional RS-485 bus inverting receiver input and driver inverting output.
14 VISOIN power_in Bus-side RS-485 supply that sets the bus-side input thresholds and output levels, and must be shorted externally to the VISO pin (absolute maximum 6 V).
15 GNDB power_in Bus-side ground and the reference point for the RS-485 bus signals (also pin 9).
16 VISO power_out Isolated power output that supplies the bus side at 3.3 V or 5 V (selected by SEL), decoupled with 0.1 µF and 10 µF capacitors to GNDB placed within 2 mm of the pin.
