Description: This device is formed by two independent NOR gates and an inverter.

Functional Diagram and/ or Package:

 


 

 

 

Pin Names

Vdd - Positive supply voltage [3 V to 15 V]

Vss - Ground

A, B, C, D, F, G, H - Inputs

X, Y, Z – Outputs

 

Operation Mode:

The logic signals are applied to the inputs of the gates and the resulted logic levels are taken from the outputs. See the truth table for more details.

Other Devices:

3-lnput NOR Gates: 4023, 4025 [buffered]. Inverters: 4009 [buffer], 4049 [buffer], 4069

Applications: NOR gates and the inverter can be used in their basic functions adding logic to a project, such as in oscillators, driving stages, and digital amplifiers.

Observations: This device is not recommended for new projects since its functions can be found in other devices of the same family. It is not always easy to find.
