ISO7841DW Datasheet PDF - TI

The ISO7841DW is a quad-channel Digital Isolator with a 8000VPK isolation voltage. It 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 an 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 ISO7841 device has three forward and one 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.

● Up to 100Mbps signalling rate

● ±100kV/µs Minimum industry leading CMTI

● Robust electromagnetic compatibility (EMC)

● Low emissions

● >40 Years isolation barrier life

● Green product and no Sb/Br

●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.
