The Texas Instrument digital isolators are triple channel digital isolators each with multiple channel configurations and output enable functions. These devices have logic input and output buffers separated by TIs silicon dioxide 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.

High electromagnetic immunity
Low channel to channel output skew
IEC 60950 1 end equipment standard
Low jitter content
