ISO7230A - Texas Instruments

ISO7230A One Megabit per Second Triple Digital Isolators

See the Product Notification section. The ISO7230A and ISO7231A 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 vol.
