GeneralGeneralGeneralGeneral The Toshiba TLP2355 consists of an infrared LED coupled with a high-gain, high-speed photo detector. It is housed in the SO6 package. The detector has a totem-pole output stage with current sourcing and sinking capabilities. The TLP2355 has an internal Faraday shield that provides a guaranteed common-mode transient immunity of 20 kV/s. The TLP2355 has a logic buffer output. An inverter output version, the TLP2358, is also available. 3. 3. FeaturesFeatures 3. 3.
