Overview
The ISO7763FDW is a high-performance, six-channel digital isolator produced by Texas Instruments. This device is part of the ISO776x family, known for its robust electromagnetic compatibility (EMC) and high isolation ratings. The ISO7763FDW is packaged in a 16-pin SOIC (DW) package and operates over a wide temperature range of –55°C to +125°C. It is designed to provide reliable isolation for CMOS or LVCMOS digital I/Os, making it suitable for various industrial and medical applications. The device features a double capacitive silicon dioxide (SiO2) insulation barrier, ensuring high electromagnetic immunity and low emissions at low power consumption.
