CA-IS3721C
Description
The CA‐IS372xC devices provide high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS digital I/O. Each isolation channel has a logic input and output buffer separated by capacitive silicon dioxide (SiO2) insulation barrier, and each channel input integrates Schmitt trigger to provide excellent noise immunity.
Key Features
- Data rate: DC to 40Mbps
- Robust isolation barrier; High lifetime: >40 years; Up to 5kVRMS isolation rating (wide‐body packages); ±150kV/μs typical CMTI
- Wide supply range: 3.0V to 5.5V
- Wide operating temperature range: -40°C to 125°C
- No start‐up initialization required
- Default output High (CA‐IS372xCH) and Low (CA‐ IS372xCL) Options
- High electromagnetic immunity
- Low power consumption; 2.6mA per channel at 1Mbps with VDDX = 5.0V; 5.2mA per channel at 40Mbps with VDDX = 5.0V
