The ISO7230C-Q1 and ISO7231C-Q1 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.
The ISO7230C-Q1 triple-channel device has all three channels in the same direction while the ISO7231C-Q1 has …
