Overview
The 74HC4051PW-Q100118, produced by Nexperia USA Inc., is a single-pole octal-throw analog switch (SP8T) designed for use in analog or digital 8:1 multiplexer/demultiplexer applications. This component is part of the 74HC4051 and 74HCT4051 series, which are known for their versatility in handling both analog and digital signals. The device 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, allowing for precise control over signal routing.
