GeneralGeneralGeneralGeneral The Toshiba TLP2108 consists of an infrared LED coupled with a high-gain, high-speed photo detector. It has two circuits built into a single SO8 package, which can reduce the mounting area. The detector has a totem-pole output stage with current sourcing and sinking capabilities. TLP2108 has an internal Faraday shield that provides a guaranteed common-mode transient immunity of 10 kV/s. The TLP2108 has a inverter output. An buffer output version, the TLP2105, is also available. 3. 3. FeaturesFeatures 3. 3.
