Overview
The TIL186-2 is an AC-input optocoupler manufactured by Texas Instruments, designed for applications requiring high-voltage isolation between input and output circuits. It features a phototransistor output stage integrated with an internal AC input structure, eliminating the need for external rectification components in alternating current signal detection. This component provides reliable electrical isolation for monitoring AC line voltages or signals in industrial and consumer electronic systems.
Feature Summary
- Integrated AC input structure suitable for direct connection to alternating current sources
- Phototransistor output stage for digital signal transmission across isolation barrier
- High-voltage isolation capability between input and output circuits
Applications
- AC line voltage monitoring
- Alternating current signal detection
- Industrial control systems requiring galvanic isolation
Procurement Notes
Verify the specific suffix '-2' against the manufacturer's official datasheet to confirm pinout configuration and packaging type. Ensure the procurement source provides documentation from Texas Instruments or authorized distributors to guarantee authenticity. Check for RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component when designing circuits that require direct coupling to AC signals without external bridge rectifiers. Consider the isolation voltage rating and output current capabilities relative to the load requirements. Evaluate the package type compatibility with your PCB layout constraints before finalizing the design.
Part Context
This device belongs to the TIL186 family of AC-input optocouplers from Texas Instruments. The family includes variants such as TIL186-1 and TIL186-3, which may differ in pin configurations or specific electrical characteristics while sharing the core AC-input functionality. These components are commonly used in power supply feedback loops and AC sensing applications.
Replacement Considerations
Consult the official Texas Instruments replacement guide for verified substitutes. Generic optocouplers may not support direct AC input without additional circuitry. Verify pin-to-pin compatibility and isolation ratings before substituting.
