4051 74HC4051 8-Channel-Mux 8-channel analog multiplexer module
This is CJMCU-4051 74HC4051 8 Channel Analog Multiplexer/Demultiplexer Sensor Module Breakout Board. 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.
1.Wide Analog Input Voltage Range: +/-5V
2.Low “ON” Resistance: 80 ohm (type) at Vcc = 4.5V; 70 ohm (type) at Vcc = 6.0V; 60 ohm (type) at Vcc = 9.0V
3.Logic Level Translation: to enable 5V to communicate with +/-5V analog signals
4.Board Size: 30 x 19 mm
