Overview
The 74HC4351D,653 is a single-pole octal-throw analog switch (SP8T) produced by Nexperia USA Inc. This component is suitable for use in analog or digital 8:1 multiplexer/demultiplexer applications. It features three digital select inputs (S0 to S2), eight independent inputs/outputs (Yn), a common input/output (Z), and two digital enable inputs (E1 and E2). The switch can be controlled to select one of the eight switches based on the select inputs, and the data at these inputs can be latched using the latch enable input (LE).
