It's behavior is the opposite of a [[NOT gate]]. The main purpose of a buffer is to regenerate the input, usually using a strong high and a strong low. A buffer has one input and one output; its output always equals its input. Buffers are also used to increase the propagation delay of circuits by driving the large capacitive loads. |

The 7407 is a TTL chip with 14 pins. Two pins are used for V<sub>DD</sub> and GND, the other 12 pins are used for the 6 independent buffers. The 4050 is a CMOS Hex Buffer with 16 pins. Two pins are used for V<sub>DD</sub> and GND, 12 pins are used for the 6 independent buffers. Pins 13 and 16 are not connected. Both chips implement the expression Q<sub>N</sub> = A<sub>N</sub> | The 7407 is a TTL chip with 14 pins.
