Prime Intact 74HC4051 8 Channel Analog Multiplexer/Demultiplexer Breakout Board for Arduino Electronic Components Electronic Hobby Kit

This is CJMCU-4051 74HC4051 8 Channel Analog Multiplexer/Demultiplexer Sensor Module Breakout Board for Arduino. 74HCT4051 is a single-pole octal-throw analog switch (SP8T) suitable for use in analog or digital 8:1 multiplexer/demultiplexer applications. The switch 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 E is HIGH, the switches are turned off. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
