PALO ALTO, Calif.--(BUSINESS WIRE)--Dec. 2, 2002
Agilent Technologies Inc. (NYSE NYSE
See: New York Stock Exchange :A) today introduced the industry's fastest optocouplers, capable of transmitting data at a 50 megabaud (MBd) rate, and ideal for use in a variety of industrial and commercial applications.
Optocouplers separate and protect sensitive circuitry to allow safe interface between high and low voltages in electronic systems. The Agilent HCPL-7723/0723 optocouplers offer a 2 nanosecond (1) One billionth of a second. Used to measure the speed of logic and memory chips, a nanosecond can be visualized by converting it to distance. In one nanosecond, electricity travels approximately a foot in a wire. (ns) pulse width pulse width Pulse duration Cardiac pacing The duration of a pacing pulse in msecs distortion, a performance breakthrough that helps maintain a high data rate over longer line distances.
"Agilent's new high-speed devices allow effective high-speed data collection and control in industrial automation applications where isolation is required," said Chong Tze Siong, vice president and general manager of Agilent's Isolation Products Division. "The new devices extend Agilent's line of isolation products, already the industry's broadest, and we are leading the industry in delivering these new products to our customers."
Field bus communication networks such as 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 make possible effective data collection and control in industrial automation. These networks, interconnecting 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. As these communication networks migrate to higher speed data transmission rates, higher speed optocouplers are required.
In addition to communications applications, Agilent's new HCPL-7723/0723 optocouplers are well suited for applications such as digital isolation for analog-to-digital conversion, digital I/O ports, computer peripheral interfaces and microprocessor system interfaces.
Agilent's new HCPL-7723/0723 high-speed optocouplers meet the most widely accepted international safety regulations. They are recognized under UL1577; approved under 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. Component Acceptance Notice No. 5; and approved according to VDE (1) (Video Display Editor) A WordStar and WordPerfect-compatible shareware word processor written by Eric Meyer.
(2) (Verband Deutscher Elektrotechniker) The German counterpart of the U.S. Underwriters Lab. 0884/06.92 (including Certificate R9650938 for TUV/ Rhineland). The use of an optical path -- essentially a short fiber optic link -- between input and output is considered the most reliable method of assuring absolute isolation.
Available in either 8-pin DIP (HCPL-7723) or more-compact SO-8 package style (HCPL-0723), these optocouplers feature the latest CMOS IC technology to achieve outstanding speed performance.
The HCPL-7723/0723 high-speed optocouplers combine a 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. LED driver IC, a high-speed LED and a CMOS detector IC within a single package. A CMOS logic input signal controls the LED driver IC, which supplies current to the LED. The detector IC 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 , 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.
U.S. Unit Prices and Availability
