The CA‐IS36xx family integrated signal and power isolation devices simplify system design and reduce board area. These devices are high‐performance, dual‐channel and four‐channel, unidirectional reinforced digital isolators with up to 5kVRMS isolation rating and ultra‐fast data rate.The integrated isolated DC‐DC converter provides up to 650mW of isolated power and different output voltage configurations. These devices offer high electromagnetic immunity and low emissions while isolating different ground domains and block high‐voltage/high‐current transients from sensitive or human interface circuitry. Each isolation channel has a logic input and output buffer separated by capacitive silicon dioxide (SiO2) insulation barrier, the integrated Schmitt trigger on each input provide excellent noise immunity.
The CA‐IS362x devices are dual‐channel digital isolators and the CA‐IS3640/CA‐IS3641/CA‐IS3642/CA‐IS3643/CA‐IS3644 devices are quad‐channel digital isolators. They offer all possible unidirectional channel configurations to accommodate any 2‐channel or 4‐channel digital I/Os design, including SPI, RS‐485, and digital I/O applications, see Name Convention for more detail, also Table 5‐1 shows the detail configurations of digital signal transmission direction for each part. The CA‐IS36xx family also features different default outputs. When the input is either not powered or is open‐circuit, the default output is low for devices with suffix L and high for devices with suffix H, see the Ordering Information for suffixes associated with each option. The individual logic supply input of CA‐IS36xxLVW
and CA‐IS36xxHVW devices allows fully compatible +3.3V and +5.0V logic on side‐A digital lines.
The CA‐IS36xx family devices are specified over the ‐40°C to +125°C operating temperature range and are available in 16‐pin SOIC wide body package.
