TIL199X

Overview

The TIL199X is a quad optoisolator manufactured by Isocom Components 2004 LTD, featuring four independent channels within a single 16-pin DIP package. It utilizes a photovoltaic output configuration with Darlington transistor outputs to provide high current transfer capabilities. The device offers an isolation voltage of 5300Vrms, ensuring robust electrical separation between input and output circuits. Key electrical parameters include a maximum forward voltage of 1.4V and a typical rise time of 100μs. The unit supports a maximum input current of 50mA and operates within a temperature range of -55°C to 100°C.

Feature Summary

• Quad channel architecture providing four isolated signal paths in a compact 16-DIP package
• Photovoltaic Darlington output structure for high gain and current handling
• High isolation voltage rating of 5300Vrms for reliable circuit separation
• Wide operating temperature range suitable for demanding industrial environments

Applications

• Industrial control systems requiring multi-channel isolation
• Power supply feedback loops with galvanic separation
• Microcontroller interface circuits for noise immunity
• Solid-state relay driver applications

Procurement Notes

Verify the specific suffix designation against official Isocom documentation to confirm pinout and performance specifications. Ensure compatibility with existing PCB footprints for 16-DIP packages. Confirm that the photovoltaic output type aligns with system requirements for drive voltage and current. Check for any updated regulatory certifications or compliance standards prior to final procurement decisions.

Selection Notes

Select this component when multiple isolated channels are required within a single package to save board space. The Darlington output is suitable for driving loads directly without additional amplification stages. Consider the 100μs switching speed limitations for high-frequency applications. Evaluate the 5300Vrms isolation barrier against system safety requirements and creepage distances.

Part Context

The TIL199X belongs to the TIL197 series of optocouplers from Isocom Components 2004 LTD. This series focuses on providing reliable isolation solutions using photovoltaic technology. The quad configuration distinguishes it from single-channel variants, offering a cost-effective solution for multi-signal isolation tasks in electronic designs.
