SP485ECN-L from MaxLinear, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RO | output | Receiver output. Drives the recovered logic-level data from the differential A/B bus pair. VOH ≥ 3.5V at IO = -4mA and VOL ≤ 0.4V at IO = 4mA. Tri-stated when RE is high; fail-safe HIGH when the differential inputs are open. |
| 2 | RE | input | Receiver output enable, active LOW. A logic LOW enables the receiver output RO; a logic HIGH places RO in a high-impedance state. Input thresholds VIH ≥ 2.0V, VIL ≤ 0.8V. |
| 3 | DE | input | Driver output enable, active HIGH. A logic HIGH enables the differential driver outputs on A and B; a logic LOW tri-states the driver outputs. Input thresholds VIH ≥ 2.0V, VIL ≤ 0.8V. |
| 4 | DI | input | Driver input. Logic-level transmit data that is converted to the differential signal on A/B when the driver is enabled. Input thresholds VIH ≥ 2.0V, VIL ≤ 0.8V; input current ±10µA. |
| 5 | GND | power_in | Ground reference for the device. |
| 6 | A | bidirectional | Non-inverting driver output / non-inverting receiver input. Half-duplex differential RS-485/RS-422 bus line. Common-mode range -7V to +12V; input resistance ≥12kΩ (typ 15kΩ); ±15kV HBM and ±15kV IEC61000-4-2 Air Discharge ESD-protected. |
| 7 | B | bidirectional | Inverting driver output / inverting receiver input. Half-duplex differential RS-485/RS-422 bus line. Common-mode range -7V to +12V; input resistance ≥12kΩ (typ 15kΩ); ±15kV HBM and ±15kV IEC61000-4-2 Air Discharge ESD-protected. |
| 8 | VCC | power_in | Positive supply. 4.75V ≤ VCC ≤ 5.25V (5V ±5%). Decouple locally to GND. |
