Additional Details

The TLP2301(TPL has a typical propagation delay of a few nanoseconds, which allows for high-speed data transmission. The common-mode transient immunity (CMTI) is an important parameter that indicates the device's ability to reject noise on the power lines. It typically has a CMTI value of several kV/μs. It comes in a small SO-5 surface mount package. It is crucial to consult the official Toshiba datasheet for precise electrical characteristics, timing diagrams, and recommended operating conditions to ensure optimal performance and safety in your specific application.

A pull-up resistor is usually required on the output side to define the logic high level. The value of the pull-up resistor should be chosen carefully to balance speed and power consumption. It's also important to ensure that the input current to the LED is within the specified range.
