Product Overview

The ISO7840DW is a quad-channel Digital Isolator with a 8000VPK 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 ISO7840 device has four forward and zero reverse-direction channels. 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.
  • ±100kV/µs Industry leading CMTI (Min)
  • Robust electromagnetic compatibility (EMC)
  • System-level ESD, EFT and surge immunity
  • Low emissions
  • >40 Years isolation barrier life
  • Green product and no Sb/Br

Applications

Industrial, Automation & Process Control, Motor Drive & Control, Power Management, Medical, Automotive

Warnings

Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
