GeneralGeneral 2. 2. GeneralGeneral The Toshiba TLP2958 consists of a GaAAs light-emitting diode coupled with a high-gain, high-speed photo detector. It is housed in the DIP8 package. The detector has a totem-pole output stage with current sourcing and sinking capabilities. The TLP2958 has an internal Faraday shield that provides a guaranteed common-mode transient immunity of 20 kV/s. The TLP2958 has an inverter output. A buffer output version, the TLP2955, is also available. 3. 3. 3. 3.
