Avago Technologies Introduces Industry's Fastest 3.3-Volt Optocoupler; 25 MBd, 3.3 V/5 V Optocoupler Features Low Pulse-Width Distortion and -40 C to +105 C Temperature Range Operation.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. , the world's largest privately held semiconductor company, today introduced the industry's fastest 3.3 V/5 V CMOS-compatible optocoupler, capable of transmitting data at 25 megabaud (MBd). This speed makes it ideal for high-speed, data-line transmission applications, such as those in industrial networking, including PROFIBUS (PROcess FIeldBUS) An industrial control network used for factory automation, process control, motion control and safety networks. Using a master/slave architecture, specialized "Profiles" are used to support each of these areas. and DeviceNet. These fieldbus networks, which interconnect sensors, actuators and controllers, typically need isolation at each interface location to increase data integrity and provide protection from power faults and ground-loop effects. Avago Technologies' new ACPL-072L high-speed optocoupler is also used in applications such as analog-to-digital conversion analog-to-digital or A/D conversion, the process of changing continuously varying data, such as voltage, current, or shaft rotation, into discrete digital quantities that represent the magnitude of the data , digital I/O ports, computer peripheral interfaces and microprocessor system interfaces. Optocouplers separate and protect sensitive circuitry, allowing for a safe interface between high and low voltages in electronic systems. "Our new high-speed optocoupler provides dual operating voltages with performance across the wide industrial operating temperature range," said Kheng-Jam Lee, worldwide marketing manager for isolation products in Avago Technologies' Optical Communication Solutions Division. "This device provides reinforced isolation and offers designers greater flexibility to select supply voltages, reduces level-shifting circuitry and lowers the power consumption." Built with the latest CMOS IC CMOS IC Complementary Metal Oxide Semiconductor Integrated Circuit technology, the Avago ACPL-072L optocoupler achieves exceptional high-speed performance with compatible 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. and TTL (1) (Time To Live) A parameter in a network packet that sets a time limit to its validity.

The ACPL-072L's approval in the following widely accepted international safety standards is pending: UL1577, 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. File CA88324 (Notice#5), and IEC/EN/DIN EN 60747-5-2. U.S. Pricing and Availability The ACPL-072L high-speed optocoupler is supplied in the SO-8 package and is priced at $3.42 each in 10,000-piece quantities.
