ISO7240CDW Description

ISO7240CDW developed by Texas Instruments is a type of quad-channel digital isolator with multiple channel configurations and output-enable functions. These devices have logic-input and logic-output buffers separated by Texas Instrument’s silicon dioxide (SiO2) isolation barrier. Used in conjunction with isolated power supplies, these devices help block high voltage, isolate grounds, and prevent noise currents from entering the local ground and interfering with or damaging sensitive circuitry.
