ADM3485EARZ-REEL from Analog Devices, 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 the receiver is enabled, RO is high if A is more than 200 mV above B and low if A is more than 200 mV below B. |
| 2 | RE | input | Receiver output enable: RE low enables RO, RE high puts RO in a high-impedance state, and RE high with DE low puts the device into shutdown. |
| 3 | DE | input | Driver output enable: a high level enables the driver differential outputs A and B, and a low level places them in a high-impedance state. |
| 4 | DI | input | Driver input: when the driver is enabled, a logic low on DI forces A low and B high, and a logic high on DI forces A high and B low. |
| 5 | GND | power_in | Ground connection, 0 V. |
| 6 | A | bidirectional | Noninverting receiver input A and driver output A, which sit on the RS-485 bus with a common-mode range of -7 V to +12 V. |
| 7 | B | bidirectional | Inverting receiver input B and driver output B, which sit on the RS-485 bus with a common-mode range of -7 V to +12 V. |
| 8 | VCC | power_in | Power supply, 3.3 V ± 0.3 V (VCC range 3.0 V to 3.6 V per the power supply specification). |
