Overview
The 74HC4051FPDEL-E, produced by Renesas Electronics America Inc., is a single-pole octal-throw analog switch (SP8T) that functions as an 8-channel analog multiplexer/demultiplexer. This component is suitable 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 inputs to voltages in excess of VCC.
