Chipanalog Micro CA-IS3640

Description

The CA-IS364x is a chip in the digital isolator series that enhances the withstand voltage and integrates a DC-DC converter. A chip for the converter. The emergence of the CA-IS364x replaces the traditional isolated power supply solutions built with discrete components, and the new enables smaller form factors to achieve complete isolation. The CA-IS3640/CA-IS3641/CA-IS3642/CA-IS3643/CA-IS3644 are quad-channel digital isolators. is a four-channel digital isolator.The CA-IS3640 chip has four forward channels, the chip has four forward channels, the CA-IS3641 chip has three forward channels and one reverse, the chip has three forward channels and one reverse, and the CA-IS3642 chip has two forward channel and reverse, the chip has two forward channels and reverse, the CA-IS3643 chip has one forward channel and three reverses, the chip has one forward channel and three reverses, the CA-IS3644 has four reverse channels with Four reverse channels. All devices have a fail-safe mode option that defaults to a low level for chips suffixed with L and a high level for chips suffixed with H if the input signal is lost.
