The ISO7840x device is a high-performance, quad-channel digital isolator witha 8000-VPK isolation voltage. This device has reinforced isolationcertifications according to VDE, CSA, CQC, and TUV. The isolator provides high electromagneticimmunity 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 highimpedance for multi-master driving applications and to reduce power consumption. The ISO7840 devicehas four forward and zero reverse-direction channels. If theinput power or signal is lost, the default output is high forthe ISO7840 device and low for the ISO7840F device.See the Device Functional Modes section for furtherdetails.
Used in conjunction with isolated power supplies, this device helps prevent noisecurrents on a data bus or other circuits from entering the local ground and interfering with ordamaging sensitive circuitry. Through innovative chip design and layout techniques, electromagneticcompatibility of the ISO7840 device has been significantly enhanced to ease system-level ESD, EFT,surge, and emissions compliance.
The ISO7840 device is available in 16-pin SOIC wide-body (DW) and extra-wide body(DWW) packages.
