Working Principles

The AM26C31IDRE4 operates on the principle of differential signaling, where data is transmitted and received as a pair of complementary signals. This technique provides high noise immunity by canceling out common-mode noise.

When enabled, the driver section amplifies the differential input signal and drives it onto the transmission line. On the receiving end, the receiver section detects the differential voltage and converts it back into a digital signal.
