Avago Technologies has announced the latest addition to its line of high-speed digital CMOS optocouplers. At 25 Megabaud (MBd), the new ACPL-772L is the industry's fastest, dual-supply voltage (3.3 V and 5 V) optocoupler in a DIP-8 package. With its unprecedented speed and the ability to support up to 5 kV in isolation voltage protection, the ACPL-772L is ideal for not only high-speed data-line transmission applications, but also those operating in higher voltages, such as test and measurement products. Avago is a leading supplier of innovative semiconductor solutions for advanced communications, industrial and commercial applications.

Avago's new ACPL-772L supports a wide temperature range of -40 degrees C to +105 degrees C, provides creepage and clearance of greater than 7mm, and offers a low pulse width distortion of 6 nanosecond (ns) maximum, which helps to maintain high data integrity over longer distances. The device exhibits a high common-mode rejection of10 kV/microsecond minimum, with 40 ns maximum propagation delay and 20 ns maximum propagation delay skew.

As the ACPL-772L can operate in dual supply voltages, designers of digital fieldbus (DeviceNet, PROFIBUS) and test and measurement applications have the flexibility in selecting supply voltages, reducing level-shifting circuitry and lowering power consumption. The ACPL-772L's approval in the following widely accepted international safety standards is pending: UL1577, CSA File CA88324 (Notice#5), and IEC/EN/DIN EN 60747-5-2.
