The ACPL-P481 is a high-speed, low-power, single-channel optocoupler in a stretched SO-8 package. This optocoupler utilizes a light-emitting diode (LED) and an integrated photodiode-transistor detector to provide electrical isolation between input and output circuits. It is designed for high-speed digital interface applications where low power consumption and high common-mode transient immunity (CMTI) are critical.

Applications:

• Isolated CANBus communications
• Isolated SPI interfaces
• Isolated RS-485 transceivers
• Industrial automation systems
• Medical equipment

Features:

• High speed: up to 10 Mbps

Additional Details:

The ACPL-P481 features a high-speed data transmission capability, which makes it suitable for fast digital communication interfaces. The low power consumption allows for energy-efficient designs. The high CMTI ensures reliable operation in environments with high voltage transients, preventing spurious switching. The stretched SO-8 package provides increased creepage and clearance distances for enhanced safety. The wide operating temperature range ensures reliable operation in harsh industrial and automotive environments.

The ACPL-P481's LED drive current is minimal. This helps in minimizing the required power to drive the optocoupler. The transistor output can drive TTL and CMOS logic directly. The device is fully compliant to industrial safety standards, and it is also RoHS compliant.
