TLP2105 is a photocoupler from Toshiba, which features high gain, high-speed photodetectors and totem-pole output stage. It utilizes GaAℓAs light emitting diodes and integrated high gain, high-speed photodetectors. It provides noninverting logic output and has an internal Faraday shield that provides a guaranteed common-mode transient immunity of ±10 kV/μs.
The Toshiba TLP2105 is a GaAs light‑emitting diode and high‑gain photodetector optocoupler housed in an 8‑pin SO package. It provides a non‑inverting logic output with a totem‑pole stage, isolation voltage up to 2500 Vrms and common‑mode transient immunity of +10 kV/µs.
