More info

The 4001 is a member of the 4000 Series CMOS range, and contains four independent NOR gates, each with two inputs. The pinout diagram, given on the right, is the standard two-input CMOS logic gate IC layout:

  • Pin 7 is the negative supply
  • Pin 14 is the positive supply
  • Pins 1&2, 5&6, 8&9, 12&13 are gate inputs
  • Pins 3, 4, 10, 11 are gate outputs

The truth table for one of the four gates is shown to the right. For more information about the NOR gate in general, see this module. The arrangement of the CMOS components is shown below:

This chip is widely available, and usually comes in a DIL-14 or SOIC-14 package.

This chip is different in pinout to the TTL 7402, but can fulfill its function if the wiring is modified.
