74F433
First-In First-Out (FIFO) Buffer Memory
General Description
The 74F433 is an expandable fall-through type high-speed
First-In First-Out (FIFO) Buffer Memory that is optimized for
high-speed disk or tape controller and communication
buffer applications. It is organized as 64-words by 4-bits
and may be expanded to any number of words or any num-
ber of bits in multiples of four. Data may be entered or
extracted asynchronously in serial or parallel, allowing eco-
nomical implementation of buffer memories.
The 74F433 has 3-STATE outputs that provide added ver-
satility, and is fully compatible with all TTL families.
