TLP113 is a photocoupler designed for digital isolation, suitable for A/D, D/A conversion, computer-peripheral interface, microprocessor system interface, etc. It features small size, high speed transmission, TTL/LSTTL compatibility, and high isolation voltage.
The TLP113 is a miniature surface‑mount photocoupler that combines a GaAs light‑emitting diode with a high‑gain, high‑speed photodetector. Its open‑collector output makes it suitable for digital isolation in microprocessor interfaces, A/D and D/A conversion, and computer‑peripheral applications.
Key specifications include a 2500 V rms isolation rating, supply voltage range of 4.5‑5.5 V, typical forward voltage of 1.65‑1.80 V at 10 mA, and propagation delays of 60‑120 ns. The device operates from –40 °C to 85 °C and is UL1577 listed. Recommended design practices such as a 0.1 µF bypass capacitor on VCC are noted.
