GeneralGeneralGeneralGeneral The Toshiba TLP2748 consists of high-output GaAAs light-emitting diode coupled with a high-gain, high-speed photo detector. It is housed in a thin SO6L package of 2.3 mm(max). The TLP2748 has guaranteed the isolation voltage 5 kVrms and compliant with international safety standards for reinforced insulation. This product can operate in power supply voltage 4.5 V to 30 V with the maximum operative temperature of 110 . Since TLP2748 has guaranteed 3 mA low supply current (I /I ), and 1.6 mA low threshold input current CCL CCH (I ), it contributes to energy saving of devices. It can drive directly from a microcomputer for a low input current. FHL The detector has a totem-pole output stage with current sourcing and sinking capabilities. The TLP2748 has an internal Faraday shield that provides a guaranteed common-mode transient immunity of 30 kV/s. The TLP2748 has an inverter output. A buffer output version, the TLP2745, is also available. 3. 3. FeaturesFeatures 3. 3.
