STMicroelectronics STISO621

The STISO621 is a dual-channel digital isolator based on the ST thick oxide galvanic isolation technology. The device provide two independent channels in opposite direction with Schmitt trigger input, providing robustness to noise and high speed input/output switching time.

Key features

• 6 kV galvanic isolation
• High data rate up to 100 Mbps
• Wide Ta range operation: from -40 ºC to 125 ºC
• High common-mode transient: > 50 kV/µs

Additional features

• Dual-channel, digital isolator with 1 – 1 channel directionality
• High data rate up to 100 Mbps
• Wide Ta range operation: -40 ºC to 125 ºC
• 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
• 6 kV galvanic isolation
• SO8 narrow and wide package options

Applications

• Optocoupler replacement in industrial application
• Industrial field bus isolation
• Battery monitor and motor drive
• Size-critical multichannel isolation
