Working Principles

The SN74CBT3244PWR operates by controlling the flow of data between two buses using the output enable (OE) pins. When the OE pin is low, the bidirectional data I/O pins are enabled and allow data transfer between the buses. Conversely, when the OE pin is high, the data I/O pins are disabled, preventing any data flow.

The switch uses CMOS technology to achieve high-speed operation while consuming minimal power. It also incorporates ESD protection to safeguard against potential damage caused by electrostatic discharge.
