Avago’s 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, Avago’s ACPL-W70L and ACPL-K73L are powered by low forward current of 4mA and consume very low current (Idd2 less than 7mA/ch). Avago’s 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.
Avago’s 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.
Pricing and Availability
Pricing for Avago’s ACPL-W70L and ACPL-K73L is $1.63 and $3.00 each respectively, in minimum quantities of 10,000. Samples are available now and production quantities will be available in July through Avago’s direct sales channel and worldwide distribution partners.
