2. General
The Toshiba TLP2270 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 TLP2270 guarantees isolation voltage 5000 Vrms and pliant 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 TLP2270 guarantees 0.8 mA low supply current (IDDL/IDDH), and 1 mA (Ta = 125 ) low threshold input current (IFLH), it contributes to energy saving of devices. It can be driven directly from a microputer by a low input current. The TLP2270 has an internal Faraday shield that provides a guaranteed mon-mode transient immunity of ±20 kV/µs.
