HXY MOSFET · RS-485/RS-422 ICs · SOP-8
MAX487ESA-HXY 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 (labelled R/RO); when RE is low and A-B ≥ +0.2V RO is high, and when A-B ≤ -0.2V RO is low, with a high-impedance output when the receiver is disabled. |
| 2 | RE | input | Receiver output enable, active low; RE low enables RO, RE high makes RO high-impedance, and RE high with DE low enters low-power shutdown. |
| 3 | DE | input | Driver output enable, active high; DE high enables the A and B driver outputs, DE low makes them high-impedance, and DE low with RE high enters shutdown. |
| 4 | DI | input | Driver input (labelled D/DI); with DE high, a low on DI forces A low and B high, and a high on DI forces A high and B low, with a rated input voltage of -0.3V to 6V. |
| 5 | GND | power_in | Ground. |
| 6 | A | bidirectional | Noninverting receiver input and noninverting driver output, with a bus voltage range of -7V to +12V and ±16kV ESD protection. |
| 7 | B | bidirectional | Inverting receiver input and inverting driver output, with a bus voltage range of -7V to +12V and ±16kV ESD protection. |
| 8 | VCC | power_in | Positive supply of +5V (5V ±0.25V in the DC characteristics), absolute maximum 6V, bypassed with a 0.1µF capacitor. |
