The TC74HC4051A/4052A/4053A are high speed CMOS ANALOG MULTIPLEXER/DEMULTIPLEXER fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
The TC74HC4051A has an 8 channel configuration, the TC74HC4052A has a 4 channel × 2 configuration and the TC74HC4053A has a 2 channel × 3 configuration.
The digital signal to the control terminal turns “ON” the corresponding switch of each channel a large amplitude signal (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 switched from the logical circuit with a single power supply of 5 V. As the ON-resistance of each switch is low, they can be connected to circuits with low input impedance.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
