Product Details

General Description

The CA-IS3720VLS is high-performance dual – channel digital isolator with up to 3.75kVRMS isolation rating. This device can operate as low as 1.8V supply voltage with up to 100Mbps data rate. The CA-IS3720VLS provides high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS digital I/O. Each isolation channel has a logic input and output buffer separated by capacitive silicon dioxide (SiO2) insulation barrier, and each channel input integrated Schmitt trigger to provide excellent noise immunity.

The CA-IS3720VLS features two channels transferring digital signals in one direction for applications such as isolated digital I/O. Also, this device offers default outputs. When the input is either not powered or is open-circuit,the default output of CA-IS3720VLS is low.

The CA-IS3720VLS is specified over the -40°C to +125°C operating temperature range and is available in 8-pin SOIC narrow body package.
