Avago Technologies Expands Family of High-Speed Dual Voltage Digital Optocouplers for Power, Industrial and Consumer Apps

SAN JOSE, Calif.—(BUSINESS WIRE)—June 30, 2008— Avago Technologies, a leading supplier of analog interface components for communications, industrial and consumer applications, today announced the expansion of its family of high-speed dual-supply voltage digital CMOS optocouplers. Avagos ACPL-W70L and ACPL-K73L digital CMOS stretched optocouplers operate at dual supply voltages of 3.3- and 5-Volts at a minimum speed of 15MBd. Moreover, these new optocouplers provide up to 5kV isolation voltage protection and are designed to achieve lower propagation delay (55ns max.) and pulse width distortion (25 ns max.) with the additional glitch-free power-up feature. This feature outputs low voltage logic during power loss and provides output logic that corresponds to the input voltage when the power supply recovers. The ACPL-W70L/K73L series targets designers of power supply, industrial, consumer, and test and measurement applications.

Avagos single channel ACPL-W70L and two channel ACPL-K73L come in SSO-6 and SSO-8 packages respectively. Both optocouplers require from 40 to 50 percent less printed circuit board (PCB) space -- compared to DIP-8 packages -- and meet 8 mm creepage and clearance requirements. Both can operate in a wide operating temperature range from -40 to 105 degrees-C. Moreover, the ACPL-W70L/K73L series incorporates the latest CMOS IC technology to achieve superior performance with very low power consumption.

As power scales down, the demand for lower supply voltage increases. In the process of power supply migration, a growing number of equipment manufacturers are looking for devices that work at both 3.3V and 5V supply voltages. In addition to supporting both 3.3V and 5V supply voltages, Avagos ACPL-W70L and ACPL-K73L are powered by low forward current of 4mA and consume very low current (Idd2 less than 7mA/ch). Avagos ACPL-W70L/K73L optocoupler series offers non-inverting output as compared to the traditional inverting output which helps to reduce power consumption in the signal pattern with less than 50 percent duty cycle.

Avagos new optocouplers include high-speed LEDs and CMOS detector ICs. Each detector incorporates an integrated photodiode, high speed transimpedance amplifier, and a voltage comparator with an output driver. The ACPL-W70L/K73L optocouplers are ideal for Digital Fieldbus isolation, multiplexed data transmission, microprocessor system interface and DC/DC converter applications.

The ACPL-W70L/K73L series meets international safety standards such as IEC/EN/DIN EN 60747-5-2, UL1577 and CSA for Reinforced Insulation.
