MAX3485ED from HTC Korea TAEJIN Tech, 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; three-state output high-impedance when RE is high (logic 1), active when RE is low (logic 0). |
| 2 | RE | input | Receiver output enable; active-low control input (VIH min 2.0V, VIL max 0.6V) that enables receiver output when low and disables to high-impedance when high. |
| 3 | DE | input | Driver output enable; active-high control input (VIH min 2.0V, VIL max 0.6V) that enables differential driver outputs A and B when high and disables to high-impedance when low. |
| 4 | DI | input | Driver input; logic input (VIH min 2.0V, VIL max 0.6V) that controls the state of differential outputs A and B when DE is high. |
| 5 | GND | power_in | Ground; power supply return path. |
| 6 | A | bidirectional | Non-inverting differential line; driven as driver output when DE is high, sampled as receiver input when RE is low, with −7V to +12V common-mode input range and ±200mV differential threshold. |
| 7 | B | bidirectional | Inverting differential line; driven as driver output when DE is high, sampled as receiver input when RE is low, with −7V to +12V common-mode input range and ±200mV differential threshold. |
| 8 | VCC | power_in | Power supply input; 3.3V nominal supply voltage with recommended operating range 3.3±5% V and absolute maximum rating 6.0V. |
