General
The TLP5771 consists of a GaAℓAs infrared light-emitting diode and an integrated high-gain, high-speed
photodetector and is housed in the 6-pin SO6L package.
The TLP5771 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 TLP5771 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 TLP5771 has rail to rail output, and this enables stable
operation and better switching performance in system.
