MM74C200 - Random Access Read/Write Memory

General Description

The MM54C200 MM74C200 is a 256-bit random access read write memory Inputs consist of eight address lines and three chip enables The eight binary address inputs are decoded internally to select each of the 256 locations The internal address register latches and address information are on the positive
