10MBd digital CMOS optocoupler draws less than 18mW, insulated to 5 kV

The ACNW261L ultra low power 10 MBd digital CMOS optocoupler from Avago Technologies draws less than 18mW and comes with a reinforced insulation working voltage of 1414 VPEAK.

Supply current is under 1.5mA over the –40 to 105°C temperature range. Both 3.3 V and 5.0 V applications are supported. The input LED current was designed to be a low 4mA. The ACNW261L features input-to-output insulation voltage of 5000 VRMS. With reinforced insulation the new optocoupler meets the IEC 607475-5-5 working voltage requirement of 1414 VPEAK, internal clearance of 1mm, external creepage of 10mm and external clearance of 9.6mm. By using an internal Faraday shield the ACNW261L has excellent common mode transient rejection performance of 20 kV/µs minimum, 35 kV/µs typical, at 1000 V common mode voltage.

An enable pin sets the CMOS output stage to a high impedance state for bus interface versatility. Slew rate controlled output ensures stable rise and fall times over temperature and operating conditions, an especially important feature for parallel interface applications. The ACNW261L operates from 3.3 V or 5.0 V power supply voltage. Applications for the new 10 MBd optocouplers include CANBus, RS232, RS485, I2C, digital Fieldbus, and analog-to-digital and digital-to-analog converter interfaces. By meeting medical equipment standard IEC 60601-1 rev 3 requirements, medical equipment suppliers can also use the new ACNW261L digital optocoupler with 1 mm internal clearance.
