High-immunity, 100-Mbps, 5.7-kVRMS reinforced single-channel 1/0 digital isolator

 

Description

The ISO7810x device is a high-performance, single-channel digital isolator with 8000 VPK isolation voltage. This device has reinforced isolation certifications according to VDE, CSA, CQC, and TUV. The isolator provides high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/Os.

The isolation channel has a logic input and output buffer separated by silicon dioxide (SiO2) insulation barrier. If the input power or signal is lost, the default output is for the ISO7810 and for the ISO7810F device. See the Device Functional Modes section for further details.

Used in conjunction with isolated power supplies, this device helps prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. Through innovative chip design and layout techniques, electromagnetic compatibility of the ISO7810x device has been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. The ISO7810x device is available in 16-pin SOIC wide-body (DW) and extra-wide body (DWW) packages.The DWW package option comes with enable pin which can be used to put the output in high impedance state for multi-master driving applications and to reduce power consumption.
