Optocoupler features digital input and output to simplify designs and lower costs

Vishay Intertechnology, Inc. has introduced a new 25MBd high-speed optocoupler providing a CMOS logic digital input and output interface for easy integration into digital systems. For industrial applications, the single-channel VOIH72A combines a low 6ns maximum pulse width distortion and 2mA maximum supply current with a wide supply voltage range from 2.7V to 5.5V and high-temperature operation to +110C.

The Vishay Semiconductors device uses a digitally controlled input LED driver with a high-speed IRED and an integrated optical photodiode IC detector in a small footprint SOIC 8 package. The optocoupler's digital input and output eradicate the necessity for external driver stages and current-limiting resistors, reducing system costs and allowing direct connection to microcontrollers to simplify designs.

With its fast switching speeds and low pulse width distortion, the device is excellent for data communication, PWM, and supplying high-voltage safety in automation equipment, motor drives, and tools. It features a minimum CMTI of 20 kV/μs. Combined with its low supply current, the optocoupler is ideal for galvanic noise isolation and breaking up ground loops while reducing power consumption.

The RoHS-compliant device is pin-to-pin compatible with competing solutions while providing wider supply voltage and temperature ranges, making it an excellent replacement for new and existing designs.

Samples and production quantities of the device are available now.
