The TLP112 is a TOSHIBA mini flat coupler. It is small, suitable for surface mount assembly, and has a maximum isolation voltage of 2500 Vrms. The switching speed is tpHL=0.8µs, tpLH=2µs(max.) (RL=4.1kΩ). It is TTL compatible.
The TLP112 is a miniature GaAs photocoupler with a light‑emitting diode and a high‑speed photodiode‑transistor detector in a single chip. It offers 2500 Vrms isolation, TTL‑compatible outputs, and a compact surface‑mount package (0.09 g). Pin configuration, switching speed (tpHL = 0.8 µs, tpLH = 2 µs) and typical application circuits are described.
Maximum ratings, detailed electrical characteristics, test circuits for switching time and common‑mode transient immunity, and current‑transfer ratio curves are provided. The document also includes handling precautions, product‑use restrictions, and recommended soldering temperature (260 °C).
