Working Principles
The SN75ALS1178NSRG4 is designed to amplify and transmit digital signals over long distances. It uses differential signaling, where the transmitted data is represented by the voltage difference between two complementary signals. This technique provides better noise immunity and allows for reliable communication even in noisy environments.
The integrated circuit consists of two drivers (A and B) and a receiver. The drivers amplify the input signals and provide differential outputs, while the receiver detects and interprets the received signals. The driver and receiver sections can be individually enabled or disabled using the DE and RE inputs, respectively.
