STISO621 [STMicroelectronics]

The STISO621 /STISO621W are dual-channel digital isolators based on the ST thick oxide galvanic isolation technology.

The devices provide two independent channels in the opposite direction with Schmitt trigger input, providing robustness to noise and high speed input/output switching time.
