9403A
First-In First-Out (FIFO) Buffer Memory
General Description
The 9403A 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 number of bits
in multiples of four. Data may be entered or extracted asyn-
chronously in serial or parallel, allowing economical imple-
mentation of buffer memories.
The 9403A has 3-STATE outputs which provide added ver-
satility and is fully compatible with all TTL families.
Features
a73 Serial or parallel input
a73 Serial or parallel output
a73 Expandable without external logic
a73 3-STATE outputs
a73 Fully compatible with all TTL families
a73 Slim 24-pin package
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
