TIL199A

Overview

The TIL199A is a quad optocoupler manufactured by Isocom Components 2004 LTD. It features four independent channels with Darlington transistor outputs housed in a 16-DIP package. The device provides an isolation voltage of 5300Vrms and a peak isolation rating of 7.5kV. It supports a maximum forward current of 50mA and includes a minimum current transfer ratio specification to ensure reliable signal transmission across the isolation barrier for digital applications.

Feature Summary

• Quad configuration providing four independent isolation channels within a single component
• High gain Darlington output stage designed for direct interface with logic circuits
• Robust electrical isolation capability suitable for high-voltage noise environments

Applications

• Digital signal isolation in multi-channel data acquisition systems
• Interface between microprocessors and high-voltage switching loads
• Isolation barriers in industrial control panels requiring multiple channel separation

Procurement Notes

Verify the specific suffix and pinout configuration against the official datasheet before integration. Confirm that the 16-DIP package dimensions match the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to distinguish from similar quad optocouplers with different output types.

Selection Notes

Select this component when multiple isolated channels are required in a compact form factor. The Darlington output offers higher current drive capability compared to standard phototransistors, reducing external resistor requirements. Consider the 16-pin package size constraints relative to available board space. Evaluate the isolation voltage rating against the system's transient voltage spikes to ensure adequate safety margins.
