{{Short description|Mapping of the physical contacts of an electronic component}} {{Distinguish|PinOut}}[[File:555 Pinout.svg|thumb|A pinout diagram of a very common [[555 timer IC|555 timer integrated circuit]] showing its eight pins (numbered 1-8) and their corresponding functions ("ground", "trigger", "output", etc.)]] In [[electronics]], a '''pinout''' (sometimes written "'''pin-out'''") is a cross-reference between the contacts, or ''pins'', of an [[electrical connector]] or [[electronic component]], and their functions. "Pinout" now supersedes the term "basing diagram" which was the standard terminology used by the manufacturers of [[Vacuum tube|vacuum tubes]] and the [[Radio Manufacturers Association]] (RMA). The RMA started its standardization in 1934, collecting and correlating tube data for registration at what was to become the [[Electronic Industries Alliance]] (EIA), which now has many sectors reporting to it and sets what is known as [[EIA standards]] where all registered pinouts and [[Registered Jack|registered jacks]] can be found.
