The ISO7230 and ISO7231 are triple-channel digital isolators each with multiple channel
configurations and output enable functions. These devices have logic input and output buffers
separated by TI’s silicon dioxide (SiO2) isolation barrier. Used in
conjunction with isolated power supplies, these devices block high voltage, isolate grounds, and
prevent noise currents on a data bus or other circuits from entering the local ground and
interfering with or damaging sensitive circuitry.
