3 Description

The ISO604x devices are high performance digital isolators designed for applications requiring up to 5000VRMS isolation rating per UL 1577. The devices are also certified by VDE, TUV, CSA, and CQC. See Section 6.7 for details.

The ISO604x devices provide high data rates at very low supply current with low propagation delay, low jitter and low channel to channel and part to part skew while isolating CMOS or LVCMOS digital I/Os. These devices come with enable pins that can be used to put the respective outputs in high impedance.

Devices in the family have channel configurations for specific numbers of forward and reverse directions across the isolation barrier, default output levels, and packaging. See the Device Comparison section for details on the device configurations. Four channel device configurations accommodate any four channel design, including SPI, RS-485, and digital I/O applications. Multiple four channel devices or combinations with two and six channel devices can be used to transmit any number of parallel I/O, SPI chip selects, status or fault signals required by the application.
