Working Principles

SN65LBC179QDR operates on the principle of differential signaling, where data is transmitted and received using two complementary signals. This allows for better noise immunity and longer transmission distances compared to single-ended signaling.

The IC uses internal circuitry to convert the single-ended input signals into differential signals, which are then amplified and transmitted over the balanced transmission lines. On the receiving end, the differential signals are converted back to single-ended signals for further processing.
