TIL196BXG

Overview

The TIL196BXG is a quad-channel optocoupler manufactured by Isocom Components. It features four independent channels within a single 16-pin DIP package, designed for high-density mounting applications. The device utilizes an AC input configuration with two infrared LEDs connected in inverse parallel to facilitate direct AC signal coupling without external rectification. It provides a high isolation voltage of 5300Vrms and supports a maximum input current of 50 mA. The output consists of phototransistors, offering a typical rise time of 100µs and fall time of 100µs. This component is suitable for industrial control and power supply isolation where space efficiency and robust electrical isolation are required.

Feature Summary

• Quad-channel architecture integrates four isolated circuits into a compact 16-pin DIP package for high-density board layouts.
• AC input capability allows direct connection to alternating current signals via internally inverse-parallel infrared LEDs.
• High dielectric isolation strength ensures reliable signal transmission across potential differences in sensitive electronic systems.

Applications

• Industrial control systems requiring multi-channel signal isolation
• Power supply units needing compact feedback loop isolation
• Smart metering devices with multiple sensor inputs

Procurement Notes

Verify the specific suffix 'BXG' against the manufacturer's latest datasheet to confirm pinout compatibility and packaging variations. Ensure that the 5300Vrms isolation rating meets the safety standards required for your target application environment. Cross-reference the 16-pin DIP footprint with your PCB design files to prevent mechanical interference during assembly.

Selection Notes

Select this component when multiple isolated channels are needed in a restricted area, as it replaces several single-channel units. Consider the 100µs switching speed; it may be insufficient for high-frequency digital communication but is adequate for standard control signals. Verify that the AC input requirement aligns with your circuit design to avoid unnecessary rectification components.

Part Context

Isocom Components specializes in providing alternative sources for discontinued or hard-to-find optocouplers. The TIL196 series is part of their portfolio aimed at replacing legacy industry-standard parts. This specific model serves as a quad-channel variant, addressing the need for increased channel density in modern electronic designs compared to older single-channel solutions.

Replacement Considerations

Check for equivalent quad-channel optocouplers from other manufacturers if supply constraints exist. Ensure that any substitute maintains the same 16-pin DIP form factor and 5300Vrms isolation rating to guarantee mechanical and electrical compatibility without redesigning the host circuit.
