The HCPL-2211-560E is a logic output optocoupler, providing electrical isolation up to 2500V RMS while regulating the input-to-output coupling capacitance to 10pF max. This isolator is optimized for low current switching applications, featuring low propagation delays, a 3.75 kV/μs common mode transient immunity, and an insulation resistance of greater than 25 GΩ.

The HCPL-2211-560E is based on a gallium arsenide infrared LED optically coupled to a photodarlington detector in a 4-Pin DIP package. The LED input can directly switch low voltage logic signals in the presence of high dV/dt and dI/dt transients. The R1 package provides a reliable and robust solution in most commercial applications.

The HCPL-2211-560E is suitable for a variety of high-speed switching applications, such as isolated-channel digital interfaces, isolated AC line monitoring, and low voltage control in industrial and automotive systems. This optocoupler is also widely used in medical, telecommunications, consumer electronics, and factory automation systems. The HCPL-2211-560E is engineered to meet the requirements of low-voltage logic systems as well as CAN bus, RS485/RS232, and Ethernet networks. It is also compliant with IEC 60950, UL1577, and UL508 standards.

The working principle of the HCPL-2211-560E optocoupler is based on the principle of light transmission. When a logic signal of a desired voltage level is applied to the LED input of the optocoupler, the LED emits light which is then detected by the photodarlington detector. The light-detected signal is then converted to an electrical form. The output of the optocoupler is then sent to an optically-isolated circuit. The light transmission ensures that the electrical signal remains isolated and does not affect the isolated circuit. This isolation prevents dangerous currents or voltages from passing through the optocoupler, which can be potentially hazardous to any electronic device.

The HCPL-2211-560E is designed for very low current switching applications. The maximum output current is 4mA, with switching speeds up to 30MHz. It can also be used to drive capacitive loads up to 10pF. In addition, the input-to-output coupling capacitance is limited to 10pF max. The HCPL-2211-560E is rated for 3.75kV/μs common mode transient immunity and greater than 25GΩ of insulation resistance, which makes it suitable for industrial or automotive applications.

In summary, the HCPL-2211-560E is a logic output optocoupler optimized for low-current switching applications, providing high-speed operation and reliable electrical isolation. This optocoupler is widely used in a variety of industrial, medical, automotive, telecommunications, consumer electronics, and factory automation applications.
