Working Principles

The SN74CB3Q3245RGYR is designed to translate signals between two voltage domains, typically used in applications where different parts of a system operate at different voltage levels. It utilizes a bidirectional level shifter circuit that automatically senses the direction of the data flow and adjusts accordingly.

When the output enable (OE) pin is low, the device is enabled, and the bidirectional data I/O pins allow data transmission between the A and B sides. The low ON-state resistance ensures minimal signal distortion during translation.
