Working Principles

SN74CBT3245CDW operates by using its bidirectional voltage-level translation capability to enable communication between two ports, A and B. The output enable (OE) pin controls the direction of data flow. When OE is low, data can be transmitted from Port A to Port B or vice versa. When OE is high, both ports are isolated, preventing any data transfer.
