The Toshiba TLP2105 consists of GaAℓAs light emitting diodes and
integrated high gain, high-speed photodetectors.
The TLP2105 is housed in the 8-pin SO package.
The photodetector has totem-pole output stage that can source and sink
current.
The photodetector has an internal Faraday shield that provides a
guaranteed common-mode transient immunity of ±10 kV/μs.
The TLP2105 provides noninverting logic output. An inverting logic
version, the TLP2108, is also available.
