Working Principles

HCPL-0872 is an optocoupler that utilizes an LED and a phototransistor to achieve signal isolation. When an input signal is applied to the LED, it emits light which is then detected by the phototransistor. This optical coupling ensures electrical isolation between the input and output sides of the device.
