Vishay — VOxx6xA Optocouplers

Vishay has introduced five new 10 MBaud optocouplers which offer low power consumption for valuable energy savings in industrial applications.  

Featuring a wide supply-voltage range of 2.7 V to 5.5 V and an open collector output, the single-channel VOH260A, VOIH060A, and VOWH260A and dual-channel VOH263A and VOIH063A may be used with low-voltage microcontrollers, and in I2C or SPI bus systems. The optocouplers are suitable for functions such as a microprocessor system interface, ground loop elimination, isolation of digital busses, high-speed analogue-to-digital or digital-to-analogue conversion, digital power control, and level shifting.  

The optocouplers use a highly efficient input LED coupled to an integrated photodetector logic gate with a strobable output. The combination of a low supply current and low typical turn-on threshold current simplifies designs by eliminating the need for an additional driver stage and allowing for direct connection to an MCU.  

High minimum common-mode transient immunity of 15 kV/μs makes the optocouplers suitable for applications operating at voltages higher than 1,000 V.
