TIL196A

Overview

The TIL196A is a quad optoisolator manufactured by Isocom Components, featuring four independent channels within a single package. It utilizes a phototransistor output configuration to provide electrical isolation between input and output circuits. The device offers a high isolation voltage rating of 5300Vrms, ensuring robust safety standards for signal transmission across potential differences. Designed for through-hole mounting, it is housed in a standard 16-DIP package, facilitating integration into various printed circuit board layouts. The component supports direct current input signals and provides reliable switching performance for digital and analog applications requiring galvanic separation.

Feature Summary

• Quad channel architecture providing four independent isolation paths
• Phototransistor output stage for efficient signal coupling
• High dielectric strength with 5300Vrms isolation capability
• Through-hole compatible 16-pin DIP packaging

Applications

• Industrial control systems requiring multi-channel isolation
• Data communication interfaces needing signal integrity
• Power supply feedback loops for safety compliance
• Microprocessor interface circuits for noise immunity

Procurement Notes

Verify the specific suffix or tape-and-reel variant if automated assembly is required, as standard versions may come in tubes. Confirm that the 16-DIP footprint matches the target PCB design before ordering. Ensure the supplier source is authorized to guarantee component authenticity and traceability. Check for any specific handling instructions related to moisture sensitivity levels if storage conditions are critical for the production environment.

Selection Notes

Select this component when multiple isolated channels are needed in a compact form factor. The phototransistor output is suitable for general-purpose switching rather than linear amplification. Consider the 5300Vrms rating for applications involving high voltage differentials. Evaluate the rise and fall times against the system's maximum switching frequency requirements to ensure adequate signal response speed without distortion.

Part Context

Isocom Components specializes in infrared optoelectronic devices, offering alternatives to discontinued industry-standard parts. The TIL196A belongs to their portfolio of high-performance optocouplers designed for reliability. As a quad-channel device, it consolidates multiple isolation functions into a single package, reducing board space compared to using individual single-channel units. This approach simplifies design complexity while maintaining high isolation standards.

Replacement Considerations

Direct pin-to-pin replacements should be verified against the original manufacturer's datasheet specifications. Ensure that the replacement part maintains the same 5300Vrms isolation voltage and phototransistor output type. Check compatibility with existing PCB footprints and thermal management requirements. Validate that the current transfer ratio and switching speeds meet or exceed the original design parameters.
