Dual-channel, 2/0, 150-Mbps digital isolator

ISO7220MDR General Description

The Texas Instruments ISO7220MDR is a top-notch dual-channel digital isolator that stands out for its robust design and reliable performance. With a reinforced isolation barrier, this isolator is ideal for use in industrial settings where durability and safety are paramount. Its two independent channels provide a secure way to transmit data between systems, shielding against voltage spikes and noise for seamless communication
