Overview
The 74HC4051PW,118 is a single-pole octal-throw analog switch (SP8T) produced by Nexperia USA Inc. This component is designed for use in analog or digital 8:1 multiplexer/demultiplexer applications. It features three digital select inputs (S0, S1, and S2), eight independent inputs/outputs (Yn), a common input/output (Z), and a digital enable input (E). When the enable input (E) is HIGH, the switches are turned off. The device includes clamp diodes on the inputs, allowing the use of current limiting resistors to interface inputs to voltages in excess of VCC.
