CA-IS3740HW High‐Speed Four‐Channel Digital Isolators Manufacturer

CA-IS3740HW 

The CA‐IS374x devices are high‐performance four‐ channel, unidirectional digital isolators with up to 5kVRMS wide‐body package isolation rating and DC to 150Mbps ultra‐fast data rate. The CA‐IS374x devices offer high electromagnetic immunity and low emissions at low power consumption 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 in automotive applications.

The CA‐IS374x family offers all possible unidirectional channel configurations to accommodate any 4‐channel design. 

The CA‐IS3740 features 4 channels transferring digital signals in one direction and output enable for the B side is active‐high. 

The CA‐IS3741 device has three forward and one reverse‐direction channels, making it ideal for applications such as isolated SPI, RS‐485 communication.

The CA‐IS3742 provides further design flexibility with two channels in each direction. Both CA‐IS3741 and CA‐IS3742 come with individual enable control pinsfor each side of the isolator which can be used to put the outputs in highimpedance for multi‐master driving applications to reduce power consumption.

The CA‐IS374x family features 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 CA‐IS374x family devices are specified over the ‐40°C to +125°C operating temperature range and are available in16‐pin SOIC wide body package, 16‐pin SOIC narrow body package and 16‐pin SSOP narrow body package .
