Working Principles

The CY74FCT2245ATQCT is a bidirectional level shifter and bus transceiver. It operates by translating signals between two different voltage domains, allowing communication between devices with incompatible logic levels. The device utilizes a combination of input/output buffers and control circuitry to achieve bidirectional voltage translation.

The direction of data flow is controlled by the DIR pin. When DIR is set to a logic high, data flows from Port A to Port B. Conversely, when DIR is set to a logic low, data flows from Port B to Port A. The OE* pin is used to enable or disable the outputs. When OE* is set to a logic low, the outputs are enabled and data can be transmitted. Conversely, when OE* is set to a logic high, the outputs are disabled.
