HCPL0731R2 Description

Short technical summary and product information.

The HCPL0731R2 from On Semiconductor is a dual-channel optocoupler featuring a high gain split Darlington photodetector. It is housed in a compact 8-pin SOIC package, suitable for applications requiring high mounting density.

 

This optocoupler is designed for low input current applications, requiring only 0.5 mA, and boasts a superior current transfer ratio (CTR) of up to 2000%. It provides 2500Vrms of isolation, making it suitable for digital logic ground isolation, telephone ring detection, and EIA-RS-232C line receivers.

 

The device operates within a temperature range of -40°C to 85°C. Its split Darlington configuration allows for lower output saturation voltage and higher speed operation compared to conventional Darlington phototransistor optocouplers. The output is compatible with CMOS and high fan-out TTL requirements.

 

Key electrical specifications include a typical CTR of 2000% and a minimum CTR of 400% at 500µA. The input power dissipation is 35 mW, and the output power dissipation is 100 mW. It supports a supply voltage of up to 18V for the HCPL0701/HCPL0731 variants.
