HD588L

Broadic · RS-485 / RS-422 ICs · SO-8

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.
