Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADUM1251WARZ device is a hot-swapable digital isolator with built-in unlatchable bidirectional communication channel compatible with the I2C interface. In this way, there is no need to divide the I2C signal into separate transmitting signal and receiving signal for the use of independent optical coupler. The device provides a bidirectional channel and a unidirectional channel and is suitable for applications that do not require a bidirectional clock.
