Texas Instruments ISO7842DWW

The ISO7842x device is a high-performance, quad-channel digital isolator with a 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. Each isolation channel has a logic input and output buffer separated by a silicon-dioxide (SiO2) insulation barrier.

This device comes with enable pins that can be used to put the respective outputs in high impedance for multi-master driving applications and to reduce power consumption. The ISO7842 device has two forward and two reverse-direction channels. If the input power or signal is lost, the default output is high for the ISO7842 device and low for the ISO7842F 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 ISO7842 device has been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance.

The ISO7842 device is available in 16-pin SOIC wide-body (DW) and extra-wide body (DWW) packages.
