Avago Technologies Expands Family of High-Speed Dual Voltage Digital Optocouplers for Power, Industrial and Consumer Apps.New CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. Optocouplers Helps to Reduce Power Consumption While Providing High Isolation Voltage, and Glitch-Free Power Up Features SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif. -- Avago Technologies Avago Technologies is an American company which was earlier the semiconductor products division of HP and later Agilent Technologies, before being spun off into a distinct legal entity. It holds more than 2,000 patents. , 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. Avago's 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 The time it takes to transmit a signal from one place to another. Propagation delay is dependent solely on distance and two thirds the speed of light. Signals going through a wire or fiber generally travel at two thirds the speed of light. Contrast with nodal processing delay. (55ns max.) and pulse width pulse width Pulse duration Cardiac pacing The duration of a pacing pulse in msecs distortion (25 ns max.) with the additional glitch-free power-up feature. This feature outputs low voltage Low voltage is an electrical engineering term that broadly identifies safety considerations of an electricity supply system based on the voltage used. While different definitions exist for the exact voltage range covered by "low voltage", the most commonly used ones include "mains 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. 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 PCB: see polychlorinated biphenyl. PCB in full polychlorinated biphenyl Any of a class of highly stable organic compounds prepared by the reaction of chlorine with biphenyl, a two-ring compound. ) 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 Looking for In the context of general equities, this describing a buy interest in which a dealer is asked to offer stock, often involving a capital commitment. Antithesis of in touch with. 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 A light sensor (photodetector) that allows current to flow in one direction from one side to the other when it absorbs photons (light). The more light, the more the current. Used to detect light pulses in optical fibers and other light-sensitive applications, it works the opposite of a , high speed transimpedance amplifier, and a voltage comparator comparator Instrument for comparing something with a similar thing or with a standard measure, in particular to measure small displacements in mechanical devices. In astronomy, the blink comparator is used to examine photographic plates for signs of moving bodies. 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 (1) (Canadian Standards Association, Toronto, Ontario, www.csa.ca) A standards-defining organization founded in 1919. It is involved in many industries, including electronics, communications and information technology. for Reinforced Insulation.
