TLP2766A(LF4,E

Logic Output Optoisolators Overview

The TLP2766A(LF4,E is a high-speed logic output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a single channel with a data rate of 20 MBd and an isolation voltage of 5000 Vrms. The device utilizes a push-pull totem pole output configuration and offers a common-mode transient immunity (CMTI) of 20 kV/µs. Electrical characteristics include a maximum propagation delay of 55 ns for both rise and fall transitions, with typical rise and fall times of 5 ns and 4 ns respectively. It operates within a supply voltage range of 2.7 V to 5.5 V and supports a maximum DC forward current of 25 mA. The component is housed in a 6-SOIC package and functions reliably across a temperature range of -40°C to +125°C.
