VOIH72A High-Speed Optocoupler

Vishay's 25 MBd high-speed optocoupler features a CMOS logic digital input and output interface for easy integration into digital systems. The VOIH72A utilizes a digitally controlled input LED driver with a high-speed IRED coupled with an integrated optical photodiode IC detector in a compact package. The optocoupler’s digital input and output eliminate the need for external driver stages and current limiting resistors, lowering system costs and enabling direct connection to microcontrollers to simplify designs. Combined with its low supply current, the device’s CMTI of 20 kV/μs makes the optocoupler ideal for galvanic noise isolation and breaking up ground loops while reducing power consumption. The VOIH72A is pin-to-pin compatible with competing solutions while offering wider supply voltage and temperature ranges, making it a perfect replacement for new and existing designs.
