The 4011 is a member of the 4000 Series CMOS range, and contains four independent NAND 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
