Working Principles

The SN74ABT16240ADLR acts as a buffer and driver for data buses. It receives input data from one side and transmits it to the other side bidirectionally. The output enable (OE) pins control the direction of data flow. When OE is high, the outputs are in a high-impedance state, allowing multiple devices to share the bus. When OE is low, the inputs are latched and the outputs reflect the input data.
