The CA-IS374x-Q1 devices are high-performance fourchannel, unidirectional digital isolators with up to 5kVRMS wide-body package isolation rating and DC to 150Mbpsultra-fast data rate. The CA-IS374x-Q1 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-Q1 family offers all possible unidirectional channel configurations to accommodate any 4-channel design, including SPI, RS-485, and digital I/O applications. The CA-IS3740-Q1 features 4 channels transferring digital signals in one direction and output enable for the B side is active-high. The CA-IS3741-Q1 device has three forward and one reverse-direction channels, making it ideal for applications such as isolated SPI, RS-485 communication.
The CA-IS3742-Q1 provides further design flexibility with two channels in each direction for isolated RS-232 or other applications. Both CA-IS3741-Q1 and CA-IS3742-Q1 come with individual enable control pins for each side of the isolator which can be used to put the outputs in high impedance for multi-master driving applications to reduce power consumption.
The CA-IS374x-Q1 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-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.
