Description

The 464A-281 is a type of IC chip used as a first-in first-out (FIFO) memory. It comes in four different variants: 8K, 16K, 32K, and 64K words by 9-bit wide memory. The data is read in the same sequential order as it was written. It is equipped with Full and Empty flags to prevent overrun and underrun. Additionally, it has three pins for easy expansion in width, depth, or both, using the depth expansion technique.
