# MAX485EBN

**XBLW** · RS-485 / RS-422 ICs · DIP-8

MAX485EBN from XBLW, in a DIP-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: with RE low, RO is high if A-B >= 200mV and low if A-B <= -200mV. |
| 2 | RE | input | Active-low receiver output enable: low enables RO, high puts RO in high impedance, and RE high with DE low enters low-power shutdown; control pin rated -0.5 to +7V. |
| 3 | DE | input | Driver output enable: high enables the driver outputs, low puts them in high impedance, and RE high with DE low enters low-power shutdown; control pin rated -0.5 to +7V. |
| 4 | DI | input | Driver input: with DE high, a low on DI drives A low and B high, and a high on DI drives A high and B low; control pin rated -0.5 to +7V. |
| 5 | GND | power_in | Ground. |
| 6 | A | bidirectional | Non-inverting receiver input and non-inverting driver output; bus-side voltage rated -8 to +12.5V. |
| 7 | B | bidirectional | Inverting receiver input and inverting driver output; bus-side voltage rated -8 to +12.5V. |
| 8 | VCC | power_in | Power supply input, operating 3.0 to 5V, absolute maximum +7V. |

## CAD (KiCad official)

- Symbol: `MAX485EBN`
- Footprint: `Package_DIP:DIP-8_W7.62mm`
- 3D model: DIP-8 (KiCad packages3D, STEP)
- 3D model files: `max485ebn-etched.step` / `max485ebn-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `max485ebn.step` / `max485ebn.glb` are the bare package body.
