Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ISO7231CQDWRQ1 is a three-channel digital isolator, each with multi-channel configuration and output enablement. These devices have logical input and output buffers separated by TI's silica (SiO2) isolation barriers. These devices are used in conjunction with isolating power sources to block high voltage, isolate ground, and prevent noisy current from data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuits.

ISO7231C-Q1 has two channels in one direction and one opposite channel. The device has an active high output that puts the output in a high impedance state when driven to a low level.
