CA-IF4220NF from Chipanalog, in a SOIC-14. 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 | NC | unconnected | This pin is not connected internally and is left floating. |
| 2 | RO | output | Receiver bus output: goes high when the receiver is enabled and VID is above VTH+ or the bus is open, shorted or idle, and is high-impedance when REB is high or open; the absolute maximum rating is VCC+0.3 V. |
| 3 | REB | input | Receiver enable input, active low: the receiver is enabled when REB is low and disabled (high-impedance output) when REB is high or open; absolute maximum voltage is 7.0 V. |
| 4 | DE | input | Driver enable input, active high: the driver outputs Y and Z are enabled when DE is high and set to high-impedance when DE is low; DE has an internal pull-down to GND so the driver is disabled when open; absolute maximum voltage is 7.0 V. |
| 5 | DI | input | Driver data input: drives Y high and Z low when DI is high and the reverse when DI is low while DE is high; DI has an internal pull-up to VCC, with VIL max 0.8 V and VIH min 2 V; absolute maximum voltage is 7.0 V. |
| 6 | GND | power_in | Ground reference for the device. |
| 7 | GND | power_in | Ground reference for the device (pin appears as GND in the pin diagram on the same page; not listed in the pin function table). |
| 8 | NC | unconnected | This pin is not connected internally and is left floating. |
| 9 | Y | output | Driver non-inverting bus output (VOD = VY - VZ is positive when DI is high); bus pin rated for ±30 V absolute maximum. |
| 10 | Z | output | Driver inverting bus output (goes low when DI is high); bus pin rated for ±30 V absolute maximum. |
| 11 | B | input | Receiver inverting input; common-mode range ±15 V with bus fault protection to ±30 V. |
| 12 | A | input | Receiver non-inverting input; common-mode range ±15 V with bus fault protection to ±30 V. |
| 13 | VCC | power_in | Positive analog supply; recommended operating range is 3 V to 5.5 V (absolute maximum 7.0 V). |
| 14 | VCC | power_in | Positive analog supply; recommended operating range is 3 V to 5.5 V (absolute maximum 7.0 V). Pins 13 and 14 are both VCC. |
