Working Principles

The CY74FCT16245CTPVCT is designed to buffer and level shift digital signals. It operates by receiving input signals on the A-side and providing corresponding output signals on the Y-side. The direction of signal flow can be controlled using the OE# (Output Enable) pin. When OE# is high, the outputs are in a high-impedance state, allowing other devices to drive the bus. When OE# is low, the inputs are latched and the outputs reflect the input data.
