10 MBd optocouplers save energy in industrial applications
The latest high-speed optocouplers from Vishay feature a wide supply range of 2.7 V to 5.5 V and an open collector output. Single- and dual-channel configurations are available.
The VOH260A, VOIH060A, VOWH260A,VOH263A and VOIH063A 10 MBaud optocouplers from Vishay offer a low maximum supply current of 5 mA per channel to reduce energy usage in industrial applications.
The low typical turn-on threshold current of 2 mA also enables use of these optocouplers in low-voltage microcontroller applications, and in systems controlled via an I2C or serial peripheral interface. This is possible because the low-power specifications eliminate the requirement for additional driver stages between the MCU and optocoupler.
These optocouplers also feature an internal shield to provide a minimum common-mode transient immunity (CMTI) of 15 kV/μs. This makes the optocouplers an ideal solution for noise isolation and ground loop elimination.
The high isolation voltage supports applications with working voltages exceeding 1 kV, increasing safety and system reliability.
