Overview
The 74HC4051BQ,115 is a single-pole octal-throw analog switch (SP8T) manufactured by Nexperia. This component is designed for use in both analog and 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 with voltages exceeding VCC.
