HCPL-073A-500E

Broadcom Limited · Transistor, Photovoltaic Output Optoisolators · SO-8

HCPL-073A-500E from Broadcom Limited, 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 ANODE 1 input Anode of the channel 1 AlGaAs input LED; the datasheet specifies forward input current IF(ON) from 40 µA to 5000 µA and a reverse input voltage limit of 2.5 V.
2 CATHODE 1 passive Cathode of the channel 1 input LED; the datasheet limits the reverse input voltage to 2.5 V.
3 CATHODE 2 passive Cathode of the channel 2 input LED; the datasheet limits the reverse input voltage to 2.5 V.
4 ANODE 2 input Anode of the channel 2 AlGaAs input LED; the datasheet specifies forward input current IF(ON) from 40 µA to 5000 µA and a reverse input voltage limit of 2.5 V.
5 GND power_in Ground reference for the detector and output stages; a 0.1-µF bypass capacitor should be connected between pins 8 and 5 as close to the device as possible.
6 VO2 output Open-collector output of channel 2 (TTL and CMOS compatible); the output voltage is limited to −0.5 V to 18 V and the output current to 60 mA per channel.
7 VO1 output Open-collector output of channel 1 (TTL and CMOS compatible); the output voltage is limited to −0.5 V to 18 V and the output current to 60 mA per channel.
8 VCC power_in Supply voltage for the detector stage, specified from 1.6 V to 18 V (absolute maximum −0.5 V to 18 V), to be bypassed with 0.1 µF to pin 5.
