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 5kV_RMS 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.
