Working Principles

The MC74VHCT259ADR2 operates based on the principles of digital multiplexing and demultiplexing. In multiplexer mode, it selects one of the eight input channels and routes it to the output based on the control inputs. In demultiplexer mode, it performs the reverse operation by distributing the input data to one of the eight output channels.

The latchable inputs allow the data to be stored and held until a latch enable signal is received. This feature ensures that the selected data remains stable even when the control inputs change.
