TIL199

Overview

The TIL199 is a quad-channel high-density optically coupled isolator manufactured by Isocom Components 2004 LTD. It integrates an infrared LED with four NPN silicon phototransistors in a single package. The device provides electrical isolation with a rated voltage of 5300Vrms. It utilizes a 16-pin DIP housing for through-hole mounting. The component supports DC input signals and delivers Darlington output configurations, enabling high current transfer capabilities suitable for digital signal transmission across isolated circuits.

Feature Summary

• Integrates four independent optical channels within a compact footprint
• Utilizes NPN silicon phototransistor output stages
• Provides high-voltage electrical isolation between input and output circuits

Applications

• Digital signal isolation in multi-channel data acquisition systems
• Interface circuits for microprocessor-based control systems
• Isolation barriers in industrial automation equipment

Procurement Notes

Verify the specific manufacturer designation when sourcing, as Isocom Components 2004 LTD may distribute products originally designed by other semiconductor manufacturers. Confirm that the 16-pin DIP package matches your PCB layout requirements. Ensure the 5300Vrms isolation rating meets the safety standards required for your specific application environment before finalizing procurement.

Selection Notes

Select this component when multiple isolated channels are required in a single package to reduce board space. The Darlington output structure offers higher gain compared to standard phototransistor outputs, making it suitable for driving loads directly without additional amplification. Verify that the 16-pin configuration fits your assembly constraints compared to lower-pin-count alternatives.

Part Context

This part belongs to the family of quad-channel optocouplers designed for high-density isolation applications. Unlike single-channel variants such as the TIL111, the TIL199 consolidates four isolation paths into one component. This consolidation simplifies circuit design for systems requiring multiple isolated digital signals while maintaining consistent performance characteristics across all channels.
