Working and Use of a Non-Inverter IC

A non-inverting buffer IC consists of non-inverters that pass the input unchanged to its output. The Non-inverter works in the opposite way of the inverter IC. The IC’s main purpose is to regenerate the input, using a strong HIGH and a strong LOW.

A non-inverting buffer has only one input and only one output and the output is equal to the input. They can be used to produce and increase the propagation delay in a circuit. The image above shows the pin configuration of the IC.

 

CD4050 IC Internal Schematic and Truth Table

The image below shows how the non-inverting buffers are present in the IC and to which pins. As mentioned earlier, the output is always equal to the input; therefore, input to A(pin 3) will be equal to the output at G (pin 2). Similarly, the outputs will be H=B, I=C, J=D, K=E, L=f.

The table below is the truth table of the CD4050 Hex buffer IC. The input and the output of the non-inverter IC are equal.

Input Signal (A,B,C,D,E,F)	Output Signal(G,H,I,J,K,L)
HIGH	HIGH
LOW	LOW
