Working Principles

The CY74FCT2244ATQCTE4 operates by receiving input signals on its A pins and providing buffered output signals on its Y pins. The direction of signal flow is controlled by the OE# (Output Enable) pin. When OE# is low, the IC is enabled, and the input signals are transmitted to the corresponding output pins. When OE# is high, the IC is disabled, and the outputs are in a high-impedance state.
