Working Principles

The SN74CBT16245CDGGR is a bidirectional bus switch that allows the connection or isolation of two separate data buses. It operates based on control signals received at the OE (Output Enable) pin, which determines whether the switch is open or closed. When enabled, the switch connects the input/output lines to the corresponding bidirectional data lines, allowing data to flow between the buses. When disabled, the switch isolates the buses, preventing any data transfer.
