Agilent Technologies introduces industry's fastest optocouplers

12/3/2002 - Agilent Technologies 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 (ns) pulse width 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 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 Component Acceptance Notice No. 5; and approved according to VDE 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 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 high-speed transimpedance amplifier, and a voltage comparator with an output driver.

U.S. Unit Prices and Availability
Both parts are available now from Agilent and its worldwide distribution partners. Pricing in 10,000-unit quantities is $4.02 for the HCPL-7723 and $4.43 for the HCPL-0723.
