GeneralGeneralGeneralGeneral The Toshiba TLP2408 consists of a GaAAs light-emitting diode coupled with a high-gain, high-speed photo detector. It is housed in the 8-pin SO8 package. The detector has a totem-pole output stage with current sourcing and sinking capabilities. The TLP2408 has an internal Faraday shield that provides a guaranteed common-mode transient immunity of 15 kV/ s. The TLP2408 has a logic inverter output. A buffer output version, the TLP2405, is also available. 3. 3. FeaturesFeatures 3. 3.
