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. |
