Working Principles

The SN74LV244ADGVR is an octal buffer IC that operates as a line driver for digital signals. It takes input signals from one or more sources and provides amplified, non-inverted output signals. The IC supports bidirectional data flow, allowing it to be used in both input and output applications.

The output enable (OE) pin controls the output state of the IC. When OE is low, the outputs are enabled and reflect the input signals. When OE is high, the outputs are in a high-impedance state, effectively disconnecting them from the bus.
