Overview
The TIL190-2 is a Darlington output optocoupler manufactured by Texas Instruments. It features a single channel with a DC input and DC output configuration housed in a 6-pin PDIP package. The device provides electrical isolation between input and output circuits, utilizing a Darlington transistor pair for high current transfer ratio performance suitable for various digital and analog signal isolation applications.
Feature Summary
- Darlington output configuration for enhanced current gain
- Single-channel optical isolation design
- DC input to DC output signal transmission capability
Applications
- Digital signal isolation in industrial control systems
- Interface between microcontrollers and power switching circuits
- General-purpose optoisolation in consumer electronics
Procurement Notes
Verify the specific revision level and packaging type when ordering. Confirm that the 6-pin PDIP format matches your PCB footprint requirements. Check for any end-of-life or obsolescence notices from the manufacturer prior to finalizing procurement plans.
Selection Notes
Select this component when high current transfer ratio is required from a single optocoupler channel. Ensure the input forward current and output voltage ratings align with the target circuit design. Consider thermal management if operating near maximum ratings.
Part Context
This part belongs to the TIL190 series of optocouplers from Texas Instruments. It is distinct from other series like INA190 which are current sense amplifiers. The TIL190-2 specifically denotes the Darlington output variant within the family.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative Darlington optocouplers based on pinout and electrical specifications.
