GeneralGeneral 2. 2. GeneralGeneral The Toshiba TLP2345 consists of high-output GaAAs light-emitting diode coupled with a high-gain, high-speed photo detector. It is housed in the SO6 package. This product can operate in power supply voltage 4.5 V to 30 V with the maximum operative temperature of 110 . Since TLP2345 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. FLH The detector has a totem-pole output stage with current sourcing and sinking capabilities. The TLP2345 has an internal Faraday shield that provides a guaranteed common-mode transient immunity of 30 kV/s. The TLP2345 has a buffer output. An inverter output version, the TLP2348, is also available. 3. 3. 3. 3.
