CA-IF4805HS

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

CA-IF4805HS 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: goes high when VID = VA − VB exceeds VTH+ and low when VID falls below VTH−, and is high-impedance when REB is high or open.
2 REB input Receiver enable, active low: the receiver is enabled when REB is low and its output is high-impedance when REB is high or open.
3 DE input Driver enable, active high: the driver outputs follow DI when DE is high and are high-impedance when DE is low; an internal pull-down disables the driver when DE is open.
4 DI input Driver data input: drives Y high and Z low when high (and the reverse when low), with an internal pull-up to VCC so the driver outputs A high and B low if left open while enabled.
5 GND power_in Ground reference for the device.
6 A bidirectional Bus port A, driver/receiver non-inverting output/input; tolerates bus common-mode range of ±15 V and fault voltage of ±30 V, with ±30 kV HBM ESD on this half-duplex (HS) part.
7 B bidirectional Bus port B, driver/receiver inverting output/input; tolerates bus common-mode range of ±15 V and fault voltage of ±30 V, with ±30 kV HBM ESD on this half-duplex (HS) part.
8 VCC power_in Power supply; the recommended supply range is 3 V to 5.5 V and the absolute maximum is 7.0 V.
