General:

The 74HC4051D, 74HC4052D are high speed CMOS ANALOG MULTIPLEXER/DEMULTIPLEXER fabricatedwith silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL whilemaintaining the CMOS low power dissipation. The 74HC4051D has an 8 channel configuration and the 74HC4052D has a 4 channel× 2 configuration. The digital signal to the control terminal turns "ON" the corresponding switch of each channel a large amplitudesignal (VCC - VEE) can then be switched by the small logical amplitude (VCC - GND) control signal. For example, in the case of VCC = 5 V, GND = 0 V, VEE = -5 V, signals between -5 V and +5 V can be switchedfrom the logical circuit with a single power supply of 5 V. As the ON-resistance of each switch is low, they can beconnected to circuits with low input impedance. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
