TC4051BFT(EL,N)

TC4051BFT(EL,N) is a multiplexer with capabilities of selection and mixture of analogue signal and digital signal. TC4051B has 8 channels configuration. The digital signal to the control terminal turns “ON” the corresponding switch of each channel, with large amplitude (VDD − VEE) can be switched by the control signal with small logical amplitude (VDD − VSS). For example, in the case of VDD = 5V VSS = 0V and VEE = -5V, signals between -5V and +5V can be switched from the logical circuit with single power supply of 5 volts. As the ON-resistance of each switch is low, these can be connected to the circuits with low input impedance.
