Working Principles

The QS3VH257S1G8 operates as a quad 2:1 multiplexer, allowing the selection of one of two input signals for each of its four channels. The output is determined by the combination of the selected inputs and the state of the output enable (OE) pins. When the OE pin is low, the corresponding channel is enabled, and the selected input is passed to the output. Conversely, when the OE pin is high, the channel is disabled, and the output remains in a high-impedance state.
