HD588E
Broadic · RS-485 / RS-422 ICs · SOP-8
HD588E from Broadic, 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. Logic-level output of the RS-485 receiver; high when A-B ≥ -50mV, low when A-B ≤ -200mV. High-impedance when /RE is high. |
| 2 | /RE | input | Receiver enable, active low. Drive low to enable the receiver output RO; drive high to place RO in high-impedance. With /RE=1 and DE=0 the part enters low-current shutdown (I_SHDN ≈ 1.8 µA typ). |
| 3 | DE | input | Driver enable, active high. Drive high to enable the differential driver onto A/B; drive low to place the driver outputs in high-impedance. |
| 4 | DI | input | Driver input. TTL/CMOS logic input; V_IH ≥ 2.0V, V_IL ≤ 0.8V. When the driver is enabled, a logic high on DI forces A high and B low; a logic low forces the inverse. |
| 5 | GND | power_in | Ground reference for the device. All voltages are referenced to this pin. |
| 6 | A | bidirectional | Non-inverting RS-485/RS-422 bus I/O. Driver non-inverting output and receiver non-inverting input. Withstands -8V to +13V bus voltage and ±16kV HBM ESD. |
| 7 | B | bidirectional | Inverting RS-485/RS-422 bus I/O. Driver inverting output and receiver inverting input. Withstands -8V to +13V bus voltage and ±16kV HBM ESD. |
| 8 | VCC | power_in | Supply voltage input. 3.3V or 5V operation (absolute maximum +6V). Bypass with a 0.1 µF ceramic capacitor to GND close to the pin. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 402 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
