Pin Names:

Vdd - Positive Supply Voltage [3 V to 15 V]

Vss - Ground

A1, B1, A2, B2, A3, B3, A4, B4 - Inputs

X1, X2, X3 - Outputs

 

Truth Table:

 


 

 

 

Operation Mode:

The logic signals are applied to the inputs and the resulting logic level appears in the output of each gate.

 

Electrical Characteristics:

 


 

 

 

Applications: In addition to use as a logic block, the 4001 can also be used in oscillators, buffers, and time delay applications.

 

Observations:

OR gates and inverters can be associated to perform as a NOR gate.

If the inputs are tied together the logic gates will operate as inverters.
