Santa Clara, Calif. Vishay Intertechnology, Inc. has introduced a new series of 10 MBd optocouplers in an SOIC-8 package that is rated for operating temperatures up to 100°C.
Available in single-and dual-channel configurations, the new SFH67xxT optocouplers offer a typical speed of 10 MBd and an operating temperature range of -40°C to 100°C. The optocouplers from Vishay Semiconductors also feature CMR values up to 10,000 V/μs, a typical pulse-width distortion (PWD) of 2.9 ns, typical propagation delay (tPHL) of 50 ns, and fast rise and fall times of 23 ns and 7 ns, respectively.
The optocouplers feature a reinforced-insulation construction that combines a highly efficient input LED with an integrated optical photodiode IC detector optimized for applications requiring high data rates such as communication bus lines, high-speed A/D and D/A converters, digital control power supplies, industrial controller I/O interfaces, and scan driver IC interfaces for plasma display panels.
The company said the new devices deliver improved output leakage current performance thanks to their NMOS open drain output structure. In addition, they provide a higher isolation replacement for signal isolation transformers, as well as noise immunity and diminished electromagnetic interference by reducing potential ground loops in electronic equipment.
The SFH67xxT optocouplers interface easily with most standard logic families and reduce design cycle time by simplifying overall system noise design considerations. The six new optocouplers are available in a standard SOIC-8 package with reinforced insulation per IEC60950 188.8.131.52 and eight pure tin leads. Three are configured with a single channel and three with dual channels, with each configuration offering a choice of CMR values of 100 V/μs, 5,000 V/μs, or 10,000 V/μs. The single-channel devices also provide an enable function on the seventh pin for strobing the detector.
Pricing for U.S. delivery starts at $1.05 each in quantities of 10,000. Samples are available now with lead times of six to eight weeks for larger orders. Volume production will be available in December 2004.
