Data Acquisition DESCRIPTION
See the Product Notification section. The ISO7240A, ISO7241A and ISO7242A are quad-channel digital isolators
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 from entering the local ground and …
