Overview
The TIL191AG is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It features a 4-pin DIP package with high-density mounting capabilities. The device integrates an infrared LED and an NPN silicon phototransistor. Key electrical parameters include a maximum forward voltage of 1.65V, a maximum input current of 60 mA, and an isolation voltage of 5.3 kVrms. The typical rise time is 2µs, while the typical fall time is 11µs. The current transfer ratio ranges from 40% to 80%.
Feature Summary
- Integrates an infrared light emitting diode and an NPN silicon phototransistor for signal isolation.
- Provides high-density mounting in a compact 4-pin DIP package.
- Ensures electrical safety with a robust isolation voltage rating.
Applications
- General purpose signal isolation in electronic circuits.
- Interface between microprocessors and peripheral devices.
- Switching applications requiring galvanic isolation.
Procurement Notes
Verify the specific suffix AG against official manufacturer documentation to confirm exact pinout and packaging variations. Ensure the component meets required isolation standards for the target application. Cross-reference datasheet specifications for thermal limits and current ratings before integration. Confirm availability through authorized distributors only.
Selection Notes
Select this component when a single-channel transistor output isolator is required. Consider the 4-pin DIP form factor for through-hole assembly constraints. Evaluate the 5.3 kVrms isolation voltage against system safety requirements. Compare the 2µs rise time against switching speed needs in the circuit design.
