The Toshiba TLP2108 consists of GaAℓAs light emitting diodes and

integrated high-gain, high-speed photodetectors.

The TLP2108 is housed in the SO8 package.

The photodetector has a 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 TLP2108 provides an inverting logic output. A noninverting logic

version, the TLP2105, is also available.
