HCPL-0631-500E

Broadcom AVAGO · Logic Output Optoisolators · SO-8-150mil

HCPL-0631-500E from Broadcom AVAGO, in a SO-8-150mil. 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 Anode 1 input LED anode for channel 1 optical isolation; maximum forward current IF = 20 mA (average), forward voltage VF = 1.4-1.75 V at TA = 25°C and IF = 10 mA.
2 Cathode 1 input LED cathode for channel 1; current-limiting resistor typically 390 Ω required in series with anode.
3 Anode 2 input LED anode for channel 2 optical isolation; maximum forward current IF = 20 mA (average), forward voltage VF = 1.4-1.75 V at TA = 25°C and IF = 10 mA.
4 Cathode 2 input LED cathode for channel 2; current-limiting resistor typically 390 Ω required in series with anode.
5 GND power_in Ground reference; 0.1 µF ceramic bypass capacitor must be connected between pins 5 and 8 with total lead length ≤20 mm.
6 VO2 output Channel 2 open collector Schottky-clamped transistor output; maximum sink current IO = 50 mA, low-level output voltage VOL = 0.35-0.6 V at IO = 13 mA and VCC = 5.5 V.
7 VO1 output Channel 1 open collector Schottky-clamped transistor output; maximum sink current IO = 50 mA, low-level output voltage VOL = 0.35-0.6 V at IO = 13 mA and VCC = 5.5 V.
8 VCC power_in Positive power supply voltage; recommended operating range VCC = 4.5-5.5 V, absolute maximum 7 V for 1 minute duration.
