Overview
The ISO7762DW 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 low emissions. The ISO7762DW is designed to isolate CMOS or LVCMOS digital I/Os, providing a reliable solution for applications requiring high data rates and strong isolation barriers.
The device features a double capacitive silicon dioxide (SiO2) insulation barrier, ensuring up to 5000 VRMS isolation rating and up to 12.8 kV surge capability. It operates over a wide supply range of 2.25 V to 5.5 V and supports data rates of up to 100 Mbps. The ISO7762DW is available in a 16-pin SOIC (DW) package and is certified by various safety standards, including UL 1577, VDE, CSA, TUV, and CQC.
