ISO7221M Datasheet Dual-channel Digital Isolators

Manufacturer: Texas Instruments

Overview: ISO7220A, ISO7220B, ISO7220C, ISO7220M, ISO7221A, ISO7221B, ISO7221C, ISO7221M SLLS755S – JULY 2006 – REVISED JANUARY 2025 ISO722x Dual-Channel Digital Isolators.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The ISO7220x and ISO7221x family devices are dualchannel digital isolators.

To facilitate PCB layout, the channels are oriented in the same direction in the ISO7220x and in opposite directions in the ISO7221x.

These devices have a logic input and output buffer separated by TI’s silicon-dioxide (SiO2) isolation barrier, providing galvanic isolation of up to 4000VPK per VDE.
