Avago Technologies - Ultra-Low Power Optocouplers for Use in Optical Isolation Applications

This new optocoupler family targets designers of communication interfaces (RS485, CANBus, and I2C), microprocessor system interfaces, and digital isolation for A/D, D/A conversion applications. Avago is a leading supplier of analog interface components for communications, industrial and consumer applications.



Avago's ultra low power 10MBd digital optocouplers combine a high efficiency light emitting diode (LED) and an integrated high gain photo detector which results in low forward drive current (1.6 mA) that will enable designers to interface the optocoupler input directly from the microcontroller output - eliminating the use of buffers to drive the LED. Moreover, the use of the LED input with a faraday shielded photodetector circuit enables 'best in class' application level common mode noise immunity (35kV/µs typical). This optocoupler family supports both 3.3V and 5V supply voltages, and provide reliable system performance in industrial temperatures ranging from -40 to +105 degrees C.



The ACPL-M61L/061L/064L/W61L/K64L family integrates a feature similar to 'under voltage lock-out' that prevents output disruption during a power supply loss or system recovery. Additionally, the output of these optocouplers is designed with a slew-rate controlled feature to allow the voltage rise and fall times to be controlled over a wide range of load capacitances.
