Overview
The 74HCT4051DB,112 is a single-pole octal-throw analog switch (SP8T) manufactured by Nexperia USA Inc. This integrated circuit is part of the 74HCT4051 series and is designed for use in both analog and digital 8:1 multiplexer/demultiplexer applications. 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 flexible control over signal routing.
