TLP2366(TPL,E

TLP2366 is a single-channel optocoupler in the Toshiba TLP family. It provides galvanic isolation between input and output, allowing a digital signal to be transferred across a safety barrier while protecting the control side from high voltages and noise.
Key points
- Input side: infrared LED; output side: photodetector (logic/ transistor output).
- Output: TTL/CMOS‑compatible, typically with a pull-up; designed for fast digital switching.
- Isolation: provides high-voltage isolation between input and output (used for safety and noise immunity).
- Applications: microcontroller or PLC isolation, motor drives, power supplies, industrial instrumentation.
- Package options: common as DIP-8 or SO-8.
Notes
- Exact specs (forward current IF, CTR, propagation delay td(on/td(off)), and isolation voltage Viso) vary by variant. Check the datasheet for the specific TLP2366 revision you’re using.
If you meant a different variant or a different manufacturer’s part, please share the exact part number or datasheet link for precise details.
