Optocoupler/LED/nixie tube/photoelectric device

These devices consist of a gallium arsenide infrared emitting diode optically coupled to a monolithic silicon phototransistor detector in a small surface mountable plastic encapsulation. They are ideal for high-density applications and do not require board mounting.

The HCPL05XX and HCPL04XX optocouplers consist of an AlGaAs LED optically coupled to a high-speed photodetector transistor in a compact 8-pin small footprint encapsulation.

The MOC256M is an AC input phototransistor optocoupler. The device consists of two anti-parallel connected IR LEDs coupled to a silicon NPN phototransistor detector. It is suitable for applications requiring detection or monitoring of AC signals. The device uses standard SOIC-8 construction.

The HCPL-0700, HCPL-0701, HCPL-0730, and HCPL-0731 optocouplers consist of an AlGaAs LED optically coupled to a high gain discrete Darlington photodetector in a compact 8-pin miniature encapsulation. The HCPL-0730 and HCPL-0731 devices have two channels per encapsulation for optimal packing density. The split Darlington configuration separates the input photodiode and first-stage gain from the output transistor, which reduces output saturation voltage and increases operating speed compared to traditional Darlington phototransistor optocouplers. The combination of a low input current of 0.5mA and a high current transfer rate of 2000% makes this series ideal for interfacing with MOS, CMOS, LSTTL and EIA RS232C inputs while ensuring output compatibility with CMOS and high fan-out TTL requirements .
