TIL193B

Overview

The TIL193B is a quad transistor output optocoupler manufactured by Isocom Components 2004 LTD. It features four independent channels within a single 16-pin DIP package, providing high-density isolation for complex circuit designs. The device offers an isolation voltage of 5300Vrms, ensuring robust protection between input and output sides. With a typical rise time of 4μs and fall time of 3μs, it supports moderate-speed signal transmission. The unit operates within a temperature range of -30°C to 100°C, making it suitable for demanding industrial environments requiring reliable electrical isolation.

Feature Summary

• Quad configuration provides four isolated channels in a compact package
• High isolation voltage ensures safety between circuits
• Transistor output facilitates direct interface with digital logic

Applications

• Industrial control systems requiring multi-channel isolation
• Data communication interfaces needing signal separation
• Power supply feedback loops for voltage regulation

Procurement Notes

Verify the specific suffix and marking on the component body to confirm the exact variant, as manufacturers may update packaging or minor specifications over time. Ensure that the procurement source provides valid traceability documentation. Cross-reference the part number against official distributor catalogs to confirm current availability status and manufacturing origin before finalizing orders.

Selection Notes

Select this component when multiple isolated channels are required within a limited board space. The quad architecture reduces assembly complexity compared to using discrete single-channel units. Consider the 5300Vrms isolation rating for applications involving significant potential differences between ground planes. Evaluate the speed requirements against the specified rise and fall times to ensure compatibility with the system's data rate.

Part Context

Isocom Components 2004 LTD specializes in infrared optoelectronic devices, offering alternatives to discontinued industry-standard parts. The TIL193 series belongs to their portfolio of transistor output optocouplers designed for general-purpose isolation. This product line targets markets seeking reliable replacements for legacy components while maintaining standard pinouts and electrical characteristics familiar to engineers.

Replacement Considerations

The ILQ2-X007T is listed as an obsolete part with available substitutes from Isocom, including ILQ2SM and ILQ2XSM. These alternatives share similar quad-channel transistor output architectures. Engineers should verify pinout compatibility and isolation voltage ratings when substituting these parts to ensure seamless integration into existing designs.
