<para component="para:flow" type="PARA">This 80-bit active-element memory
is a monolithic Schottky-clamped transistor-transistor logic (STTL) array
organized as 16 words by 5 bits. A memory system using the SN74S225 can easily
be expanded in multiples of 16 words or of 5 bits as shown in Figure 2. The
3-state outputs controlled by a single output-enable (<over>OE</over>) input
make bus connection and multiplexing easy.</para>
<para component="para" type="PARA">A first-in, first-out (FIFO) memory is
a storage device that allows data to be written into and read from its array
at independent data rates. This FIFO is designed to process data at rates
from dc to 10&thinsp;MHz in a bit-parallel format, word by word. </para>
<para component="para" type="PARA">Reading or writing is done independently
utilizing separate asynchronous data clocks. Data can be written into the
array on the low-to-high transition of either load-clock (CLKA, CLKB) input.
Data can be read out of the array on the low-to-high transition of the unload-clock
(UNCK IN) input (normally high). Writing data into the FIFO can be accomplished
in one of two manners:</para>
<list level="LEVEL2" component="List:sb_n1"><prefix>1</prefix>.<?Tab Type="regular">In
applications not requiring a gated clock control, best results will be achieved
by applying the clock input to one of the clocks while tying the other clock
input high.</list>
<list level="LEVEL2" component="List:sb_n1"><prefix>2</prefix>.<?Tab Type="regular">In
applications needing a gated clock, the load clock (gate control) must be
high in  order for the FIFO to load on the next clock pulse.</list>
<para component="para" type="PARA">CLKA and CLKB can be used interchangeably
for either clock gate control or clock input.</para>
<para component="para" type="PARA">Status of the SN74S225 is provided by three
outputs. The input-ready (IR) output monitors the status of the last word
location and signifies when the memory is full. This output is high whenever
the memory is available to accept any data. The unload-clock (UNCK OUT) output
also monitors the last word location. This output generates a low-logic-level
pulse (synchronized to the internal clock pulse) when the location is vacant.
The third status output, output ready (OR), is high when the first word location
contains valid data and UNCK IN is high. When UNCK IN goes low, OR will go
low and stay low until new valid data is in the first word position. The first
word location is defined as the location from which data is provided to the
outputs.</para>
<para component="para" type="PARA">The data outputs are noninverted with respect
to the data inputs and are 3-state with a common control input (<over>OE</over>).
When <over>OE</over> is low, the data outputs are enabled to function as totem-pole
outputs. A high logic level forces each data output to a high-impedance state
while all other inputs and outputs remain active.The clear (<over>CLR</over>)
input invalidates all data stored in the memory array by clearing the control
logic and setting OR to a low logic level on the high-to-low transition of
a low-active pulse.</para>
<para component="para" type="PARA">The SN74S225 is characterized for operation
from 0&deg;C to 70&deg;C.</para>
