Working Principles

The CY74FCT2245ATSOCT is a bus transceiver that facilitates bidirectional data transfer between two buses, typically operating at different voltage levels. It uses a combination of input/output buffers and control logic to ensure seamless data transmission. The direction control pin (DIR) determines the direction of data flow, while the output enable pins (OE A and OE B) enable or disable the outputs. When enabled, the IC transfers data from Bus A to Bus B or vice versa, depending on the direction control signal.
