|Description||Quad 2-Input NAND Gate|
|Basic TTL Counterpart||7400|
|Truth Table (One Gate)|
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
The truth table for one of the four gates is shown to the right. For more information about the NAND gate in general, see this module.
This chip is different in pinout to the TTL 7400, but can fulfill its function if the wiring is modified.
