Working Principles

The SN74AC245NSRG4 operates based on the principles of bidirectional data transfer. It uses a combination of control signals (DIR and OE) to determine the direction of data flow and enable/disable the output drivers. When the DIR signal is set to a specific logic level, the IC transfers data from one bus to another in the corresponding direction. The OE signal controls the output drivers, allowing them to be enabled or disabled as needed.
