Working Principles

The SN74CBT3244DBR is a digital switch that acts as a multiplexer/demultiplexer. It allows bidirectional voltage-level translation between two different voltage domains. The device uses address inputs to select the desired channel, enabling the transmission of data between the input/output pins. The output enable pin (OE) controls the direction of data flow. When OE is low, the device is enabled, and data can be transmitted bidirectionally. Conversely, when OE is high, the device is disabled, and the data lines are in a high-impedance state.
