HXY MOSFET · RS-485 / RS-422 ICs · SOP-8
HSN75176BDR from HXY MOSFET, in a SOP-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: driven high when VA > VB by 200 mV and low when VA < VB by 200 mV. |
| 2 | RE | input | Receiver output enable, active low: when RE is high the receiver output is high-impedance. |
| 3 | DE | input | Driver output enable, active high: when DE is low the driver outputs are high-impedance; with DE high the device transmits, and with DE low and RE low it receives. |
| 4 | DI | input | Driver input: a low level on DI drives A high and B low, and a high level on DI produces the opposite states. |
| 5 | GND | power_in | Ground, the negative supply terminal. |
| 6 | A | bidirectional | Non-inverting receiver input and non-inverting driver output; the driver has short-circuit current limiting and thermal shutdown, and the receiver is fail-safe to a high output on an open input. |
| 7 | B | bidirectional | Inverting receiver input and inverting driver output; the driver has short-circuit current limiting and thermal shutdown, and the receiver is fail-safe to a high output on an open input. |
| 8 | VCC | power_in | Positive supply, specified for 5 V single-supply operation with an absolute maximum of 10 V. |
