Working Principles

The SN74LVC244APWE4 is an octal buffer/line driver that operates on CMOS logic. It features non-inverting inputs and outputs, meaning the output signal follows the input signal's logic level. The device has 3-state outputs, allowing multiple devices to share a common bus without interference.

When the Output Enable (OE) pin is low, the outputs 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 wide supply voltage range of 1.65V to 5.5V, making it compatible with various systems. It also offers high-speed operation with a maximum propagation delay time of 3.7 ns at 3.3V.
