New high-speed 10 MBd optocouplers in single- and dual-channel configurations feature +100

Vishay Electronic : 03 May, 2006  (New Product)
Vishay Intertechnology, Inc. today announced a new series of 10 MBd optocouplers in an SOIC-8 packaged rated for operating temperatures up to +100
Vishay Intertechnology, Inc. today announced a new series of 10 MBd optocouplers in an SOIC-8 packaged rated for operating temperatures up to +100 C.

The new SFH67xxT optocouplers feature a reinforced-insulation construction combining 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.

Along with a typical speed of 10 MBd and operating temperature range of −40 C to 100 C, the new optocouplers from Vishay Semiconductors feature CMR values up to 10,000 V/s, typical pulse-width distortion of 2.9 ns, typical propagation delay of 50 ns, and fast rise and fall times of 23 ns and 7 ns, respectively.

Vishay's 10 MBd optocouplers 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 six new optocouplers are available in a standard SOIC 8 package with reinforced insulation per IEC60950 2.10.5.1 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/s, 5,000 V/s, or 10,000 V/s. The single-channel devices also feature an enable function on the seventh pin for strobing the detector.
