General
The TLP5771H consists of an infrared LED and an integrated high-gain, high-speed photodetector and is housed
in the 6-pin SO6L package.
The TLP5771H 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 TLP5771H 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 TLP5771H has rail to rail output, and this enables stable
operation and better switching performance in system.
