74HC4051 multiplexer - 5 pcs

This is a set of 5 pcs 74HC4051 multiplexers.The 74HC4051 is a single pole octal turn analog switch (SP8T) suitable for use in analog or digital 8: 1 multiplexer / demultiplexer applications.The switch has three digital selection inputs (S0, S1 and S2), eight independent inputs / outputs (Yn), a common input / output (Z) and a digital enable input (E). When E is high, the switches are off. Inputs include clamp diodes. This allows the use of current limiting resistors to couple inputs at voltages higher than VCC.
