TIL199G

Overview

The TIL199G is a quad optocoupler manufactured by Isocom Components 2004 LTD, featuring four independent channels within a single 16-pin DIP package. It utilizes Darlington transistor outputs to provide high current transfer ratios, specifically a minimum of 500% at an input current of 2mA. The device offers robust electrical isolation with a voltage rating of 7500V peak and 5300Vrms. Designed for surface or through-hole mounting, it operates across a wide temperature range from -55°C to 100°C, ensuring reliability in demanding industrial environments.

Feature Summary

• Quad configuration integrating four independent optocoupler channels in a compact 16-pin dual in-line package
• High-density Darlington output structure enabling significant current gain and high current transfer ratios
• Enhanced isolation capability supporting high-voltage transient immunity between input and output circuits

Applications

• Industrial control systems requiring multi-channel signal isolation
• Solid-state relay driver circuits utilizing high-gain output stages
• Computer interface modules for data transmission isolation

Procurement Notes

Verify the specific suffix and packaging variant against the official datasheet to ensure compatibility with your assembly process. Confirm that the Darlington output characteristics align with your load requirements. Check for RoHS compliance status if environmental regulations apply to your manufacturing facility. Ensure the 16-pin DIP footprint matches your PCB design constraints before finalizing procurement.

Selection Notes

Select this component when multiple isolated channels are required in a single footprint to save board space. The Darlington output is suitable for driving loads directly without additional amplification stages. Consider the higher power dissipation inherent in Darlington structures compared to standard phototransistors. Verify that the 5300Vrms isolation rating meets the safety standards of your target application environment.
