Vishay 10MBd optocouplers: low current, wide V Range

Vishay Intertechnology has introduced five new 10MBd high speed optocouplers that provide low power consumption to save energy in industrial applications.

Featuring a wide voltage supply range of 2.7V to 5.5V and an open collector output, the single-channel VOH260A, VOIH060A, and VOWH260A and dual-channel VOH263A and VOIH063A enable usage with low voltage microcontrollers and I²C and SPI bus systems.

Offered in DIP-8, SMD-8, and SOIC-8 packages, the new Vishay Semiconductors devices utilise a highly efficient input LED coupled to an integrated photodetector logic gate with a strobable output. The optocouplers combine a low supply current of 5mA maximum per channel with a low typical turn-on threshold current of 2mA typical, which simplifies designs by eliminating the need for an additional driver stage for a direct microcontroller connection.

The VOH260A, VOIH060A, VOWH260A, VOH263A, and VOIH063A are ideal for data communications, high speed A/D and D/A conversion, level shifting, and providing high voltage safety in automation equipment, motor drives, and tools. The devices feature an internal shield that provides a guaranteed common mode transient immunity (CMTI) of 15kV/μs minimum. Combined with their low turn-on threshold and supply current, this makes the optocouplers ideal for noise isolation and breaking up ground loops in these applications.

The RoHS-compliant devices offer maximum rated withstand isolation voltage up to 5,000 VRMS and provide isolation distances from 5mm to 10mm to cover a wide range of requirements, including those of applications with working voltages exceeding 1000V.

Samples and production quantities of the high speed optocouplers are available now, with lead times of six weeks.
