Toshiba TLP2748 TP E optocoupler with inverter logic and buffer output version in thin SO6L package
Product Overview
The Toshiba TLP2748 is a high-output GaAAs infrared LED coupled with a high-gain, high-speed photo detector, housed in a thin SO6L package. It offers guaranteed isolation voltage of 5 kVrms and compliance with international safety standards for reinforced insulation. Designed for energy saving, it operates with low supply current (3 mA) and low threshold input current (1.6 mA), allowing direct drive from microcomputers. The device features a totem-pole output stage with current sourcing and sinking capabilities and an internal Faraday shield for high common-mode transient immunity (30 kV/s). This product has an inverter output; a buffer output version, the TLP2745, is also available.
