HD588L from Broadic, in a SO-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: with the receiver enabled, RO goes high when V(A)-V(B) > -50 mV and goes low when V(A)-V(B) < -200 mV. |
| 2 | RE | input | Receiver output enable, active low: RO is valid when RE is low, the receiver is disabled when RE is high, and RE high with DE low puts the whole chip into shutdown. |
| 3 | DE | input | Driver output enable: driver is enabled when DE is high and disabled with outputs in high impedance when DE is low, and DE low with RE high puts the whole chip into shutdown. |
| 4 | DI | input | Driver input: a low level forces the non-inverting output low and the inverting output high, and a high level forces the non-inverting output high and the inverting output low. |
| 5 | GND | power_in | Ground reference for all device voltages; absolute ratings are referenced to this pin. |
| 6 | A | bidirectional | Bus interface, non-inverting driver output and non-inverting receiver input, rated -8 V to +13 V absolute maximum. |
| 7 | B | bidirectional | Bus interface, inverting driver output and inverting receiver input, rated -8 V to +13 V absolute maximum. |
| 8 | VCC | power_in | Positive supply for 3.3 V or 5 V operation (absolute maximum +6 V), to be bypassed to GND with a 0.1 µF capacitor. |
