VOH260A, VOIH060A, VOWH260A, VOH263A, and VOIH063A High-Speed Optocouplers

Vishay's five 10 MBd high-speed optocouplers provide low power consumption to save energy in industrial applications. Featuring a wide voltage supply range of 2.7 V to 5.5 V and an open collector output, the single-channel VOH260A, VOIH060A, and VOWH260A along with the dual-channel VOH263A and VOIH063A enable usage with low-voltage microcontrollers and I²C and SPI bus systems. The devices utilize a highly efficient input LED coupled to an integrated photodetector logic gate with a storable 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 for a direct microcontroller connection. Together with their low turn-on threshold and supply current, the devices’ guaranteed common mode transient immunity (CMTI) of 15 kV/μs minimum makes them ideal for noise isolation and breaking up ground loops. The optocouplers’ isolation distances cover a wide range of requirements, including applications with working voltages exceeding 1,000 V.
