MaxLinear · RS-485 / RS-422 ICs · SOIC-8
SP485EEN-L from MaxLinear, 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: goes HIGH when A - B is at least +0.2 V, LOW when A - B is at most -0.2 V, and HIGH when the inputs are open (fail-safe). |
| 2 | RE | input | Receiver output enable, active LOW: a logic LOW enables the receiver and a logic HIGH disables it, with input thresholds of 2.0 V (min high) and 0.8 V (max low). |
| 3 | DE | input | Driver output enable, active HIGH: a logic HIGH enables the differential driver outputs and a logic LOW tri-states them, with input thresholds of 2.0 V (min high) and 0.8 V (max low). |
| 4 | DI | input | Driver input that sets the differential driver outputs A and B, with input thresholds of 2.0 V (min high) and 0.8 V (max low). |
| 5 | GND | power_in | Ground connection for the device. |
| 6 | A | bidirectional | Non-inverting driver output and receiver input, with a receiver common-mode range of -7 V to +12 V. |
| 7 | B | bidirectional | Inverting driver output and receiver input, with a receiver common-mode range of -7 V to +12 V. |
| 8 | VCC | power_in | Positive supply; must be held between 4.75 V and 5.25 V. |
