TLP2345

Photocouplers Infrared LED & Photo IC TLP2345 TLP2345 1. Applications Intelligent Power Module Signal Isolation Programmable Logic Controllers (PLCs) High-Speed Digital Interfacing for Instrumentation and Control Devices 2. General The Toshiba TLP2345 consists of high-output infrared LED 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 (ICCL/ICCH), and 1.6 mA low threshold input current (IFLH), it contributes to energy saving of devices. It can drive directly from a microcomputer for a low input current. 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/µs. The TLP2345 has a buffer output. An inverter output version, the TLP2348, is also available. 3.
