Product Details

General Description

The CA-IS37XX –Q1 devices are high-performance, low-power, multi-channel, unidirectional digital isolators with up to 5kVRMS isolation rating and ultra-fast data rate (up to 150Mbps). 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.

All devices of CA-IS374x family feature 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. The CA-IS37XX-Q1 family devices are specified over the -40°C to +125°C operating temperature range and are available in 16-pin SOIC wide-body package.
