About Isolated Interface

Our isolated interface products integrated the digital isolation and transceivers into single chip, such as the isolated RS-485/RS-422 transceivers, isolated CAN transceivers, isolated I2C, isolated digital I/O; We also offer the isolated interface products with internal power supply, that include isolated RS-485/RS-422 transceivers with DC-DC converter, isolated CAN transceivers with switching power supply. These high-integration solution can help customers to increase reliability and simplify designs while providing the highest levels of protection on the market.

The CA-IS302X devices are complete dual-channel, galvanic digital isolators with up to 3.75kVRMS (narrow-body package)/5kVRMS (wide-body package) isolation rating and ±150kV/μs typical CMTI.

The CA-IS305X family of devices is galvanically-isolated controller area network (CAN) transceiver that has superior isolation and CAN performance to meet the needs of the industrial applications.

The CA-IS308X family of devices is a galvanically-isolated RS-485/RS-422 transceiver that has superior isolation and RS485 performance to meet the needs of the industrial applications.

The CA-IS309X family of devices is galvanically-isolated RS-485/RS-422 transceivers with built-in isolated DC-DC converter, that eliminates the need for a separate isolated power supply in space constrained isolated designs.

The CA-IS398X family of isolated octal digital inputs are optimized for industrial 24V digital input applications. All devices can be configured for Type 1, Type 2, or Type 3 inputs with a few external components and each channel can sink and source current.
