Broadcom ACPL-K64L-560E AC/DC Input 2-Channel Optocoupler Surface Mount 8-Pin SO Package

The Broadcom ACPL-K64L-560E is a low-power, high-performance AC/DC input optocoupler designed for industrial and electronic applications requiring isolation and noise immunity. Featuring two optocoupler channels integrated in an 8-pin SO surface mount package, it facilitates compact PCB designs with reliable signal transfer and electrical isolation.

This device combines an AlGaAs LED with a high gain photodetector and CMOS output stage, providing efficient operation with a low forward voltage of 1.7 volts and a low input current of 1.6 mA typical. Each channel consumes a maximum IDD current of 1.3 mA, allowing microcontrollers and digital logic devices to drive the input easily.

The optocoupler offers robust performance against electrical noise with a high common-mode rejection ratio of at least 20 kV/μs at 1000 volts, ensuring signal integrity in noisy industrial environments. The high isolation voltage rating of 5000 Vrms supports safe operation in high voltage applications.

Operating over a temperature range from -40°C to 105°C, this optocoupler ensures reliable performance under harsh conditions. The device meets strict safety and environmental standards including IEC/EN/DIN EN 60747-5-5, CSA, RoHS, and UL 1577 certifications, making it suitable for industrial, instrumentation, and power supply applications.

Typical switching speeds are high with rise and fall times of 12 nanoseconds, enabling data rates of 10 MBd minimum. The package’s small outline surface mount form and 8-pin configuration simplify integration into compact circuit boards and automated assembly lines.

Maximum forward voltage of 1.7V for efficient LED drive. AC/DC input current type for versatile control signals. Wide operating temperature range from -40°C to 105°C. 5000Vrms isolation voltage for safety and signal integrity.

Low power consumption with 1.3mA maximum IDD per channel. High common-mode noise rejection performance. Fast switching times (12ns rise/fall time) for high-speed applications. Compliance with multiple international safety and environmental standards.

The Broadcom ACPL-K64L-560E is widely applicable in industrial control systems, digital isolator functions, data acquisition systems, and signal transmissions requiring galvanic isolation between input and output circuits. Its robust electrical characteristics and compliance make it an ideal component for quality-conscious electronics and embedded system designs.
