Description
4001norgate.jpg

This chip contains four (QUAD) NOR gates, each with 2 inputs, which can operate individually or in combination.


Features and Applications

Uses:

NOR logic gate. Found on electronic resource boards - Short Time Delay 1, Flip Flop 1, Set Reset Flip Flop, Motor Speed Control

In normal use:

Pin 14 (+3 to 15v) is connected to the positive (+ve) supply. Pin 7 is connected to the negative (-ve) supply. All unused inputs should be connected to the positive supply.

Note: The output signal is low powered and normally needs amplification to drive output devices.

Each logic gate works as shown in the truth table.

Input 1 (eg pin 1) Input 2 (eg pin 2) Output (eg pin 3)
0 0 1
0 1 0
1 0 0
1 1 0

Connecting two inputs of a gate together (eg 1 & 2) makes the gate act like a NOT gate or INVERTER.
