The 4049 is a member of the 4000 Series CMOS range, and contains six independent NOT gates, each with two inputs. The pinout diagram, given on the right, is the standard two-input CMOS logic gate IC layout:
- Pin 1 is the positive power supply
- Pin 8 is the ground
- Pins 3, 5, 7, 9, 11 and 14 are gate inputs
- Pins 2, 4, 6, 10, 12, and 15 are gate outputs
