The '''9400 Series''' (officially '''4700 Macrologic Series Bipolar Family''') was a [[microprocessor family|family]] of {{arch|4}} [[bipolar]] multi-chip [[bit-slice microprocessor]] designed by [[Fairchild Semiconductor]]. The series was introduced in 1975. Around the same time Fairchild introduced the {{fairchild|4700|4700 series}} which was a similar family using bipolar technology instead.
