CA-IF4850HS

Chipanalog · RS-485 / RS-422 ICs · SOIC-8

CA-IF4850HS from Chipanalog, in a SOIC-8. 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 RO output Receiver output: when REB is low, RO is high if (VA - VB) > VTH+ and low if (VA - VB) < VTH-, and RO is high-impedance when REB is high.
2 REB input Active-low receiver enable: low (or tied to GND) enables the receiver and high disables it with RO in high-impedance; REB is internally pulled up to VCC, so a floating pin disables the receiver.
3 DE input Active-high driver enable: high enables the driver, while low or open puts the A and B outputs in high-impedance (DE has an internal pull-down).
4 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; DI is internally pulled up to VCC, so an open input drives A high.
5 GND power_in Ground reference for the device.
6 A bidirectional RS-485/RS-422 bus non-inverting receiver input and driver output; bus pins withstand ±30 V fault voltage and the common-mode range is ±15 V.
7 B bidirectional RS-485/RS-422 bus inverting receiver input and driver output; bus pins withstand ±30 V fault voltage and the common-mode range is ±15 V.
8 VCC power_in Supply input for 3.0 V to 5.5 V; place a bypass capacitor of at least 0.1 µF between VCC and GND close to the pin.
