Working Principles

The SN65ALS180DRG4 is designed to transmit and receive high-speed digital signals over long distances. It utilizes differential signaling, where data is transmitted as the voltage difference between two complementary signals (A and B). This allows for noise immunity, as common-mode noise is rejected by the receiver.

The driver amplifies the differential input signals and provides a high-speed output signal (Y and Z) with low voltage swing. The receiver then detects the differential voltage and converts it back into a digital signal.

The enable pin (EN) controls the operation of both the driver and receiver. When EN is high, the device is enabled, and when it is low, the device is disabled, reducing power consumption.
