1. Applications
• Factory Networking
• High-Speed Digital Interfacing for Instrumentation and Control Devices
• I/O Interface Boards
2. General
The Toshiba TLP2261 consists of a high-output infrared LED coupled with a high-speed photo-diode-transistor
chip. It is housed in the SO8L package. It is housed in a thin SO8L package of 2.35 mm (max). The TLP2261
guarantees isolation voltage 5000 Vrms and compliant with international safety standards for reinforced
insulation. It has two circuits built into a single SO8L package, which can reduce the mounting area.
This photocoupler guarantees operation at up to 125 and on supplies from 2.7 V to 5.5 V. Since TLP2261
guarantees 2 mA low supply current (IDDL/IDDH), and 1.6 mA (Ta = 125 ) low threshold input current (IFHL),
it contributes to energy saving of devices. It can be driven directly from a microcomputer by a low input current.
The TLP2261 has an internal Faraday shield that provides a guaranteed common-mode transient immunity of
±20 kV/µs.
