Working Principles

The SN74CBT3245ADBQRE4 is a bidirectional voltage level translator that allows seamless communication between devices operating at different logic voltage levels. It uses a combination of CMOS technology and integrated circuit design to achieve fast and efficient signal switching.

The device operates by controlling the channel select inputs (A1-A8, B1-B8) to determine the direction of data flow. When the OE (Output Enable) pin is low, the device is enabled, and the selected channel connects the corresponding bidirectional data I/O pin (I/O1-I/O8) to the input or output bus, depending on the channel configuration.

The SN74CBT3245ADBQRE4 also provides ESD protection on all pins, ensuring reliable operation in environments prone to electrostatic discharge.
