Combinational Logic: Inverters and Buffers

Operation of an inverter (Example: VHC04)
Operation of an inverter (Example: VHC04)

Example: 74VHC04

An inverter is a logic gate whose output (Y) is the inverse of its input (A).

Operation of a buffer (Example: VHC244)
Operation of a buffer (Example: VHC244)

Example: 74VHC244

A buffers increase the drive capability to increase the number of connectable signal lines, and perform waveform shaping.
A buffer does not perform logical operations.
