7.1 Overview

The SNx4AHC125 devices have four integrated bus buffer gates. Each gate can be individually controlled from their respective output enable pins or tied together and controlled simultaneously. This allows for control of up to four different lines from one device. Often times a microcontroller have multiple function options for a single pin. By using GPIO pins to enable specific buffers, the SNx4AHC125 can act as a multiplexer to select a specific data line depending on what pin function is selected on the microcontroller. At the same time, the lines that are not selected are isolated from the pin.
