'''Fairchild 100K''' ('''F-100K'''; '''100xxx''') was a family of very high-speed [[discrete logic chips]] and {{arch|8}} [[bit-slice]] chips introduced by [[Fairchild Semiconductor]] in the early-1970s but did not reach high availability until the later part of the decade. This series was implemented using [[emitter-coupled logic]] (ECL) making those chips considerably faster than comparable [[Schottky TTL]]-based chips. The 100K family were an improved version of the 10K which was originally introduced by [[Motorola]] and was later also manufactured by Fairchild. Many early high-speed systems and [[supercomputers]] made use of those chips.

Making use of ECL meant system designers were confronted with high power consumption which reduced the usefulness of those chips. It's part of the reason why most systems that used those chips only used them where high speed was vitality needed and even then expensive special cooling was often needed.

In April 1980 Fairchild introduced an expansion to the standard discrete logic chips, the {{fairchild|F220}} (10022x) series of micro-programmed {{arch|8}} [[bit-slice]] chips. The sub-family was composed of 5 chips featuring 1,000-gate density and sub-nanosecond delays.
