Overview
The TIL194BG is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features a transistor output and utilizes a 4-DIP package. The device provides an isolation voltage of 5.3 kVrms with a peak withstand voltage of 7.5 Vpk. This component integrates an infrared light emitting diode input connected in inverse parallel, designed for AC input applications.
Feature Summary
- Integrates dual infrared LEDs in inverse parallel configuration for AC signal handling
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes a standard 4-pin DIP package for through-hole mounting
Applications
- AC signal isolation in industrial control systems
- Interface circuits for microprocessor-based systems requiring galvanic separation
- Solid-state relay driver applications
Procurement Notes
Verify the specific suffix 'BG' against official manufacturer documentation to confirm pinout and packaging variations. Ensure compatibility with required isolation voltage ratings for the target application environment. Cross-reference datasheet specifications for thermal limits and forward voltage requirements before integration into circuit designs.
Selection Notes
Select this component when AC input detection or isolation is required without additional rectification stages. The inverse-parallel LED structure simplifies circuit design for alternating current signals. Verify that the 5.3 kVrms isolation rating meets safety standards for the intended electrical interface.
Part Context
The TIL194BG belongs to the TIL194 series of optically coupled isolators from Isocom Components. This series typically includes variants like the TIL195 and TIL196, which share similar structural characteristics but may differ in specific electrical parameters or packaging options within the same product family.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Consult official manufacturer cross-reference guides for verified alternatives.
