The ACPL-P481-560E is an optoisolator from Avago Technologies, belonging to Logic Output optoisolator family. It offers exceptional performance over-voltage protection, isolation voltage and creepage between input and output, as well as high temperature stability. This device is designed to interface between the digital signal levels and CMOS input/output logic integrated circuits, providing logic level isolation and voltage interface between circuits working at different voltage levels.

The ACPL-P481-560E is self-biased, using an internal current sink to produce precise high/low threshold levels between 10 mA and 20 mA. The optoisolator contains a green emitting alInGaP LED coupled to a high speed amplifier/transistor output stage. Its operating voltage is 5.5V DC and forward current is 10 mA±1 mA, with a reverse voltage of 5V max. It features high maximum DC input voltage (27V) and low AC/DC leakage current (µA), making it suitable for applications in which transient protection is a key requirement.

The ACPL-P481-560E is designed to act as a logic-level transmitting device, allowing the input and output signals to operate safely at different voltage levels without any galvanic connection. This is made possible thanks to the highly efficient LED/photodetector configuration and the operating principle of optical isolation. In operation, the LED emits light which is detected by the photodiode and translated into an electrical signal, thus isolating two different circuits and providing electrical protection.

The ACPL-P481-560E is suitable for use in a wide range of applications. It is commonly used as an interface for computers, networking equipment, power supplies, industrial control systems, automotive electronics, etc. It can be used to protect printed circuit boards (PCBs), provide simplified data transmission between two systems, and to provide reliable electrical isolation. This optoisolator is also used in applications such as optical switches, motion control systems, motor control systems, contact closure systems, solar energy application, and so on.

The ACPL-P481-560E is designed to offer reliable and high-performance isolation. It features stable switching behavior over wide temperature range (from -40°C to 85°C) and provides excellent EMI/RFI shielding. The storage temperature range is from -40°C to 125°C. The RoHS compliant design of the optoisolator ensures that it is environmentally friendly and safe to use in any environment.

The ACPL-P481-560E from Avago Technologies is a reliable, high-performance optoisolator, designed to provide electrical isolation between two circuits operating at different voltage levels. Its high maximum DC input voltage and low AC/DC leakage currents make it suitable for a wide range of applications, such as computers, industrial control systems and automotive electronics. Its stable switching behavior and EMI/RFI shielding make it an ideal choice for applications that require high performance.
