CA-IS3742LW-Q1
Active
Automotive, Quad Channel Standard Digital Isolators
The CA‐IS374x‐Q1 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‐Q1 devices offer high electromagnetic immunity and low emissions at low power consumption while isolating different ground domains 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 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.
