Overview
The ISO7763DW is a high-performance, six-channel digital isolator produced by Texas Instruments. This device is part of the ISO776x family, which is designed to provide robust electromagnetic compatibility (EMC) and high isolation ratings. The ISO7763DW is packaged in a 16-pin SOIC (DW) package and operates over a wide temperature range of –55°C to +125°C. It is used to isolate CMOS or LVCMOS digital I/Os, ensuring high-electromagnetic immunity and low emissions at low power consumption.
