Description：

The STISO621 /STISO621W are dual-channel digital isolators based on the ST thickoxide galvanic isolation technology.The devices provide two independent channels in the opposite direction with Schmitttrigger input, providing robustness to noise and high speed input/output switchingtime.

Features：

• Dual channel, digital isolator with 1 – 1 channel directionality

• High data rate up to 100 Mbps

• Wide tamb range operation: - 40ºC to 125ºC

• High common-mode transient: >50k V/µs

• From 3 V to 5.5 V, supply levels

• 3.3 V and 5 V level translation

• Low-power consumption

• Pulse width distortions < 3 ns

• 6k V galvanic isolation in SO8W package

• SO8 narrow and wide package options

• Safety and regulatory approvals
