ADM3075EARZ-REEL7 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 − B) ≥ −50 mV and low if (A − B) ≤ −200 mV. |
| 2 | RE | input | Receiver output enable: a low level enables RO, a high level places RO in high impedance, and RE high with DE low puts the device into low power shutdown. |
| 3 | DE | input | Driver output enable: a high level enables the driver differential A and B outputs, a low level places them in high impedance, and DE low with RE high puts the device into low power shutdown. |
| 4 | DI | input | Driver input: when the half-duplex driver is enabled, a logic low forces A low and B high, and a logic high forces A high and B low. |
| 5 | GND | power_in | Ground reference for the device. |
| 6 | A | bidirectional | Noninverting receiver input A and noninverting driver output A on the RS-485/RS-422 bus, with ±15 kV ESD protection on the bus pin. |
| 7 | B | bidirectional | Inverting receiver input B and inverting driver output B on the RS-485/RS-422 bus, with ±15 kV ESD protection on the bus pin; common-mode input range is −7 V to +12 V. |
| 8 | VCC | power_in | Power supply, 3.3 V ±10%; bypass VCC to GND with a 0.1 µF capacitor. |
