Working Principles

The SN74ABT244ADBRG4 is a non-inverting buffer with 3-state outputs. It operates by receiving input signals and amplifying them to provide higher current drive capability. The device supports bidirectional data flow, allowing it to act as a buffer between different logic families.

When the Output Enable (OE#) pin is low, the outputs (Y1-Y4) are active and reflect the input signals. When OE# is high, the outputs are in a high-impedance state, effectively disconnecting them from the bus.

The IC operates within a specified supply voltage range and provides voltage level translation between different logic families, making it suitable for interfacing between systems with varying voltage requirements.
