Overview
The TIL118-2 is a transistor output optocoupler manufactured by Texas Instruments. It features an infrared emitting diode coupled to an NPN phototransistor, providing electrical isolation between input and output circuits. The device offers a high isolation voltage of 2500Vrms, ensuring safety in high-voltage environments. Key electrical parameters include a current transfer ratio suitable for logic interfacing and fast switching speeds. It operates within a standard temperature range and is designed for compact applications requiring reliable signal transmission across isolated domains.
Feature Summary
- Provides galvanic isolation between control and load circuits
- Integrates an infrared LED with an NPN phototransistor detector
- Ensures high voltage safety with robust dielectric isolation
Applications
- General-purpose digital signal isolation
- Logic interface circuits
- Solid-state relay driver applications
Procurement Notes
Verify the specific package variant and tape-and-reel specifications against the official Texas Instruments datasheet before ordering. Confirm that the component meets all required isolation voltage ratings for your specific circuit design. Ensure compatibility with your manufacturing process regarding lead-free status and RoHS compliance as stated in the product documentation.
Selection Notes
Select this component when a cost-effective, general-purpose optocoupler is needed for low-speed digital isolation. Consider the current transfer ratio requirements for your specific load conditions. Evaluate the package size constraints against available footprint options. Compare performance metrics such as propagation delay and isolation voltage against alternative devices if higher speed or stricter safety standards are required.
Part Context
The TIL118-2 belongs to the broader family of Texas Instruments optocouplers, which are widely used for electrical isolation in industrial and consumer electronics. This specific model represents a standard transistor-output configuration, distinct from logic-output or triac-output variants within the same manufacturer's portfolio. It serves as a fundamental building block for isolating microcontroller signals from higher voltage power stages.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source material. Consult the official Texas Instruments replacement guide or distributor cross-reference tools for verified alternatives.
