MX3085E from Wuxi Maxinmicro, in a SOP-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: while RE is low, RO is high when A-B is greater than or equal to -50 mV and low when A-B is less than or equal to -200 mV. |
| 2 | RE | input | Receiver output enable, active low: RO is enabled when RE is low and high-impedance when RE is high; with RE high and DE low the device enters low-power shutdown. |
| 3 | DE | input | Driver output enable: the driver outputs are active when DE is high and high-impedance when DE is low; with RE high and DE low the device enters low-power shutdown. |
| 4 | DI | input | Driver input: when DE is high, a low on DI forces the non-inverting output low and the inverting output high, and a high on DI forces the non-inverting output high and the inverting output low. |
| 5 | GND | power_in | Ground. |
| 6 | A | bidirectional | Non-inverting receiver input and non-inverting driver output. |
| 7 | B | bidirectional | Inverting receiver input and inverting driver output. |
| 8 | VDD | power_in | Positive supply pin; the datasheet specifies 3.0 V ≤ VCC ≤ 5.5 V. |
