Introduction

CA-IS376x is a high-performance six-channel digital isolator with precise timing characteristics and low power dissipation. When isolating CMOS digital I/O, CA-IS376x devices provide high electromagnetic immunity and low emissions. All device versions feature Schmitt-trigger inputs for high noise immunity.

The logic input and output buffers of each isolation channel are separated by a silicon dioxide insulating barrier. CA-IS3760 has all six channels in the same direction; CA-IS3761 has five forward and one reverse channel; CA-IS3762 has four forward and two reverse channels; CA-IS3763 has three forward and three reverse channels. All devices offer a fail-safe mode option. If the input-side power supply fails or the signal is lost, devices with suffix L default to a low output, while devices with suffix H default to a high output.

CA-IS376x devices feature high isolation capability, helping to prevent noise and surges on data buses or other circuits from reaching the local ground and interfering with or damaging sensitive circuitry. High CMTI capability ensures correct transmission of digital signals. CA-IS376x devices are available in 16-pin narrow-body SOIC and 16-pin wide-body SOIC packages. All products carry an isolation rating of 3.75kV RMS, and wide-body package versions support insulation withstand voltage up to 5kV RMS.
