Optocouplers are latch-up and oscillation free

A series of 1MBd high speed optocouplers featuring an open collector transistor output with Schmitt-Trigger functionality for easy integration into digital systems have been released by Vishay. The VOH1016A series devices provide a low typical turn-on threshold current of 0.65 mA and maximum supply current of 1.0 mA, and are designed for programmable logic controllers, serial data communication and bus systems, and switch mode power supplies.

The devices utilise a highly efficient input LED coupled with an integrated optical photodiode IC detector in DIP-6 and SMD-6 packages.

The optocouplers' low turn-on threshold current and supply current — combined with a guaranteed minimum common mode transient immunity (CMTI) of 10 kV/μs — make the devices perfect solutions for galvanic noise isolation and breaking up ground loops in digital applications.

In addition, the VOH1016A series optocouplers feature a wide power supply range from 3V to 15V to enable isolated level shifting in applications using different voltage domains.

The RoHS-compliant devices are latch-up and oscillation free, feature guaranteed on / off threshold hysteresis, and offer high data rates to 2MHz and a maximum rated withstand isolation voltage of 5000 VRMS.

Samples and production quantities of the VOH1016A series are available now, with lead times of six weeks.
