ISO7231C (ACTIVE) Triple Channel, 2/1, 25Mbps, Digital Isolator

 

Recommended alternative parts

  • ISO7731  - The device has the SAME FUNCTIONALITY and PINOUT as the compared device but is NOT an exact equivalent.   Pin-to-pin upgrade with higher isolation, stronger CMTI, wider supply range, and better immunity and robustness

Description

The ISO7230 and ISO7231 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 voltage, isolate grounds, and prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry.
