MAX3485ESA-MS from MSKSEMI, in a SOP-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 | tri_state | Receiver output; logic high when /RE low and A-B ≥ -10mV, logic low when A-B ≤ -200mV, high impedance when /RE high. |
| 2 | /RE | input | Receiver enable input; drive low to enable receiver output RO based on differential bus input, drive high for RO high impedance, use with DE low for low-power shutdown mode. |
| 3 | DE | input | Driver enable input; drive high to enable driver outputs on A and B bus lines, drive low for high impedance state, use with /RE high for low-power shutdown mode. |
| 4 | DI | input | Driver data input; with DE high, logic low drives A output low and B output high, logic high drives A output high and B output low. |
| 5 | GND | power_in | Ground; 0V reference point for all voltages. |
| 6 | A | bidirectional | Non-inverting receiver input and non-inverting driver output; RS-485 bus A signal with ±15V bus withstand voltage range and 1/8 unit load input impedance. |
| 7 | B | bidirectional | Inverting receiver input and inverting driver output; RS-485 bus B signal with ±15V bus withstand voltage range and 1/8 unit load input impedance. |
| 8 | VCC | power_in | Positive power supply; operating voltage range 3.0V to 5.5V, maximum rating +7V, continuous power dissipation maximum 470mW in SOP-8 package. |
