74F403A
First-In First-Out (FIFO) Buffer Memory
General Description
The 74F403A is an expandable fall-through type high-
speed First-In First-Out (FIFO) Buffer Memory optimized
for high-speed disk or tape controllers and communication
buffer applications. It is organized as 16-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 74F403A has 3-STATE outputs which provide added
versatility and is fully compatible with all TTL families.
