ISO7741: Isolator can be up to 150Mbps

Part Number: ISO7741
Other Parts Discussed in Thread: ISO7641FM, ISO7241M, ISO7821LLS

Is there any device able to compete with MAX14131? customer need speed up to 150Mbps for VFD application. thanks.

  • Hi Brian,

    We currently have ISO7641FM (preferred) and ISO7241M that support 150Mbps datarate. ISO77xx can only support datarate upto 100Mbps.

    Using digital isolators with only single ended channels for 150Mbps datarate on a real customer application is generally challenging to achieve. It involves very careful PCB design, routing and impedance matching techniques. Instead using differential channels for 150Mbps datarate reduces the dependency on PCB design to some extent. TI has LVDS isolator ISO7821LLS which supports 150Mbps datarate and also supports very high isolation ratings.

    Please see if any of the above recommended devices meet your requirement, thank you.
