Working Principles

The CY74FCT16245TPACT is a data buffer/transceiver that facilitates the bidirectional transfer of digital signals between two ports, A and B. It operates based on the principles of CMOS logic, utilizing a combination of transistors to amplify and transmit digital signals. The input/output voltage levels are compatible with TTL logic, allowing seamless integration with other TTL devices.

The direction of data flow is controlled by the output enable pins (OE1 to OE8). When an output enable pin is active, the corresponding port's outputs are enabled, allowing data to be transmitted from that port. Conversely, when an output enable pin is inactive, the outputs of the corresponding port are disabled, preventing data transmission.
