ISO7840FDWWR Information

General Description

The ISO7840x digital isolator stands out for its exceptional performance and reliability, boasting an impressive 8000-V isolation voltage and reinforced certifications from reputable organizations like VDE, CSA, CQC, and TUV. This quad-channel isolator is designed to provide high electromagnetic immunity and low emissions, making it an ideal choice for applications requiring reliable isolation of CMOS or LVCMOS digital I/Os. The logic input and output buffers in each channel are isolated by a silicon-dioxide barrier, ensuring optimal signal integrity and protection

Key Features

Improved Signal Integrity
Enhanced EMI/RFI Immunity
Safe and Reliable Design
Wide Operating Temperature
