GATEMODE · RS-485 / RS-422 ICs · SOP-8
GM3085N from GATEMODE, 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 | output | Receiver output; when RE is low and A-B ≥ -50mV, RO outputs high; when A-B ≤ -200mV, RO outputs low; when RE is high, RO is high impedance. |
| 2 | RE | input | Receiver output enable, active low; when RE is low RO output is valid; when RE is high RO is high impedance; device enters low power shutdown mode when RE is high and DE is low. |
| 3 | DE | input | Driver output enable, active high; when DE is high driver output is valid; when DE is low output is high impedance; device enters low power shutdown mode when RE is high and DE is low. |
| 4 | DI | input | Driver input; when DE is high, low level on DI forces true output low and complementary output high; high level on DI forces true output high and complementary output low. |
| 5 | GND | power_in | Ground connection, reference potential for all circuit operations. |
| 6 | P1 | bidirectional | Receiver input and driver output with polarity adaptive function; differential line connection for RS-485/RS-422 communication with ±15kV ESD protection. |
| 7 | P2 | bidirectional | Receiver input and driver output with polarity adaptive function; differential line connection for RS-485/RS-422 communication with ±15kV ESD protection. |
| 8 | VCC | power_in | Positive supply voltage; recommended supply voltage range 3.0V to 5.5V, maximum 7V. |
