10K

Fairchild 100K (F-100K) was a family of very high-speed discrete logic chips introduced by Fairchild Semiconductor in the mid-1970s. The 100K 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 but was also manufactured by Fairchild. Many early high-speed systems and supercomputers made use of those chips.

Overview

In the mid-1970s Fairchild introduced the 100K which was an improved version of the original 10K family. 100K-based parts found their way into many early high-performance systems. For example, the Floating Point Systems FPS-264 64-bit floating-point co-processor which was introduced in February 1985 performed 4 to 5 times faster than its predecessor, FPS-164, by simply switching from to 100K ECL from Schottky TTL; this was all done without making any architectural changes and maintaining 100% software compatibility.
