Working Principles

The ISL3159EIBZ-T operates based on the principles of differential signaling. It uses two complementary signals, one positive and one negative, to transmit data over a twisted-pair cable. This differential signaling provides excellent noise immunity, allowing reliable communication even in electrically noisy industrial environments.

The driver section of the IC converts the digital input signal into a differential output, while the receiver section receives the differential signal and converts it back into a digital format. The receiver is equipped with short-circuit protection to prevent damage in case of a fault on the communication line.
