The optocouplers provide low power consumption to save energy in industrial applications. The single-channel VOH260A, VOIH060A, and VOWH260A and dual-channel VOH263A and VOIH063A have a wide voltage supply range of 2.7 to 5.5V and an open collector output. They are for use with with low voltage microcontrollers and I²C and SPI bus systems, says the Vishay Semiconductors.

Offered in DIP-8, SMD-8, and SOIC-8 packages, the optocouplers use an 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.

All five devices are suitable 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. They feature an internal shield that provides a guaranteed common mode transient immunity (CMTI) of 15kV/μs minimum. This means the optocouplers are also suitable for noise isolation and breaking up ground loops in these applications.

The RoHS-compliant devices offer maximum rated withstand isolation voltage up to 5,000V RMS and provide isolation distances from 5.0 to 10mm to cover a wide range of requirements, including those of applications with working voltages exceeding 1,000V.

Samples and production quantities are available now, with lead times of six weeks.
