ApplicationsApplications Intelligent Power Module Signal Isolation Programmable Logic Controllers (PLCs) High-Speed Digital Interfacing for Instrumentation and Control Devices 2. 2. 2. 2. GeneralGeneralGeneralGeneral The Toshiba TLP2348 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 TLP2348 has guaranteed 3 mA low supply current (I /I ), and 1.6 mA low threshold input current(I ), it contributes to energy saving of devices. It can drive CCL CCH FHL directly from a microcomputer for a low input current. The detector has a totem-pole output stage with current sourcing and sinking capabilities. The TLP2348 has an internal Faraday shield that provides a guaranteed common-mode transient immunity of 30 kV/ s. The TLP2348 has an inverter output. A buffer output version, the TLP2345, is also available. 3. 3. FeaturesFeatures 3. 3.
