The H11L33S is a Logic Output optoisolator, meaning it outputs logic levels. This makes it especially useful in logic-level switching applications where low voltage, high current drives are desired.

Working Principle

The H11L33S optoisolator works by using light to isolate the input from the output. The input circuit is an LED connected to a transistor, and the output circuit is another transistor connected to an LED. When current is applied to the LED in the input circuit, it emits light, which in turn activates the transistor in the output circuit, activating the output.

The H11L33S uses a photovoltaic cell to detect the LED in the output circuit. When the LED in the output circuit is activated, the photovoltaic cell is able to detect the change in light levels, and provides a logic level output. This logic level output can then be used to trigger other logic level devices.

The isolation voltage of the H11L33S is rated up to 5kVDC, which makes it suitable for a variety of industrial applications. The device also has a high-speed switching time of 10ns, and a low power consumption of 0.3W.
