TIL196B

Overview

The TIL196B is a high-density quad optocoupler manufactured by Isocom Components. It features four independent channels with AC input and phototransistor output, housed in a 16-pin DIP package. The device provides an isolation voltage of 5300Vrms. Designed for applications requiring robust electrical isolation between circuits, it utilizes infrared technology to transmit signals across the isolation barrier without direct electrical connection.

Feature Summary

• Quad configuration providing four independent signal paths within a single package
• AC input capability allowing direct connection to alternating current sources
• Phototransistor output stage for standard digital or analog switching applications
• High isolation voltage rating ensuring safety in high-voltage environments

Applications

• Industrial control systems requiring isolated signal transmission
• Power supply feedback loops for voltage regulation
• Microprocessor interface circuits for noise immunity
• Solid-state relay driver circuits

Procurement Notes

Verify the specific manufacturer designation when sourcing, as Isocom Components often produces compatible replacements for legacy parts. Confirm the package type and pinout match your existing PCB footprint. Ensure the supplier provides official datasheets to validate the 5300Vrms isolation rating and channel count. Check for any specific ordering suffixes that may indicate tape-and-reel packaging versus bulk quantities.

Selection Notes

Select this component when a quad-channel solution is required to save board space compared to individual dual-channel units. The AC input feature simplifies circuit design for mains-powered applications. Consider the 5300Vrms isolation level if operating in high-noise or high-voltage industrial environments. Verify that the phototransistor output speed meets the system's timing requirements.

Part Context

Isocom Components specializes in infrared optoelectronic devices and has over 40 years of industry expertise. The company was established following the acquisition of Litronix by Siemens and later became independent. They are known for producing high-quality optocouplers and sensors, often serving as alternative sources for discontinued components from other major manufacturers.

Replacement Considerations
