ADM2484EBRWZ-REEL7 from Analog Devices, in a SOIC-16-300mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD1 | power_in | Power supply, logic side (3.3 V or 5 V). Decoupling capacitor to GND1 required; value should be between 0.01 µF and 0.1 µF. |
| 2 | GND1 | power_in | Ground return for the logic side of the isolation barrier. |
| 3 | RxD | output | Receiver data output on the logic side. Reflects the state of the differential A/B bus inputs when the receiver is enabled. |
| 4 | RE | input | Receiver enable input, active low. When low, the receiver is enabled; when high, the receiver output (RxD) is high-impedance (disabled). |
| 5 | DE | input | Driver enable input, active high. When high, the differential driver (Y, Z outputs) is enabled; when low, the driver outputs are high-impedance. |
| 6 | TxD | input | Transmit data logic input to the driver. Logic level referenced to VDD1/GND1. |
| 7 | NC | unconnected | No connect. This pin must be left floating. |
| 8 | GND1 | power_in | Ground return for the logic side of the isolation barrier (second GND1 pin). |
| 9 | GND2 | power_in | Ground return for the isolated bus side of the isolation barrier. |
| 10 | NC | unconnected | No connect. This pin must be left floating. |
| 11 | Y | output | RS-485/RS-422 driver noninverting output. In half-duplex operation, tie externally to receiver input A (pin 14). |
| 12 | Z | output | RS-485/RS-422 driver inverting output. In half-duplex operation, tie externally to receiver input B (pin 13). |
| 13 | B | input | RS-485/RS-422 receiver inverting differential input. Line input resistance typ 96 kΩ; true fail-safe biased. |
| 14 | A | input | RS-485/RS-422 receiver noninverting differential input. Line input resistance typ 96 kΩ; true fail-safe biased. |
| 15 | GND2 | power_in | Ground return for the isolated bus side (second GND2 pin). |
| 16 | VDD2 | power_in | Power supply, bus side (isolated 3.3 V). Decoupling capacitor to GND2 required; value should be between 0.01 µF and 0.1 µF. |
