Working Principles

The QS32245PAG operates by selectively connecting the input/output channels of buses A and B. The enable control inputs (OEA, OEB) determine the direction of signal flow. When OEA is low and OEB is high, data flows from bus A to bus B. Conversely, when OEA is high and OEB is low, data flows from bus B to bus A. The bidirectional nature of the switch allows seamless communication between two independent data buses.
