Toshiba TLP290-4 4-Channel Transistor Optoisolator

This Toshiba TLP290-4 optoisolator provides four isolated transistor-output channels in one device, helping pass signals between circuits while maintaining galvanic isolation.

It supports AC or DC input drive and provides transistor outputs, making it suitable for interface and control designs where the input and output sides need to remain electrically separated.

Refer to the Toshiba datasheet for detailed application information, recommended operating conditions and package guidance.
