General

The TLP5774H consists of an infrared LED and an integrated high-gain, high-speed photodetector and is housed

in the 6-pin SO6L package.

The TLP5774H is 50 smaller than the 8-pin DIP package and meets the reinforced insulation class requirements

of international safety standards.

Therefore the mounting area can be reduced in equipment requiring the safety standard certification.

The TLP5774H has an internal faraday shield that provides a guaranteed common-mode transient immunity of

±35 kV/μs.

In particular, this photocoupler guarantees operation with a low threshold input current. It allows bufferless

direct drive from a microcomputer. In addition, the TLP5774H has rail to rail output, and this enables stable

operation and better switching performance in system.
