National Semiconductor Posts 22 Percent Year-to-Year Revenue Growth, 60.7% Gross
Margin and Earnings of 37 Cents Per Share for Third Quarter of Fiscal Year 2006

o Q3 FY06 revenues were $547.7 million, slightly higher than Q2 FY06
o Gross margin reached 60.7%, up from 57.2% in Q2 and 52.7% in Q3 FY05
o GAAP net income rose to $130.1 million, up from $114.7 million in Q2 and $77.4
  million in Q3 FY05
o Outlook for Q4 FY06 revenue is 2% to 4% up sequentially from Q3

SANTA  CLARA,  Calif.,  March 9,  2006 -- National  Semiconductor  Corporation
(NYSE:NSM)  today  reported GAAP net income of $130.1  million,  or 37 cents per
share, on revenues of $547.7 million for the third quarter of fiscal 2006, which
ended February 26, 2006.

National's third quarter revenues were 22 percent higher than the $449.2 million
revenues  recorded in the third quarter of fiscal 2005,  and $3.7 million higher
than the $544.0 million revenues  reported in Q2 FY06. During the third quarter,
revenues from broader  markets served through  National's  distribution  channel
were  strong,  which more than offset an expected  seasonal  decline in revenues
from products that serve wireless handsets.

National's Q3 GAAP net income was 13 percent higher  sequentially and 68 percent
higher  year-to-year.  The  Company  previously  reported  net  income of $114.7
million,  or 32 cents per share, for the prior quarter and $77.4 million,  or 21
cents  per  share,   for  the  third  quarter  of  fiscal  2005.  The  Company's
profitability  improvement in Q3 was driven primarily by a significant  increase
in quarterly gross margin, which exceeded the 60 percent milestone for the first
time in National's history.

The Company's gross margin of 60.7 percent in Q3 FY06 compares with gross margin
of 57.2 percent last quarter and 52.7 percent in the third quarter of last year.
The continued  improvement in National's  gross margin is a direct result of the
Company's focus on growing its  higher-value  Analog product  portfolio.  In the
third  quarter,  gross margin was also aided by  improvements  in  manufacturing
volume and efficiencies.

"Business  conditions  were stronger than we had originally  anticipated,"  said
Brian L.  Halla,  chairman  and CEO of National  Semiconductor.  "We reached our
interim goal of 60 percent gross margin earlier than we expected and at the same
time continued to gain market share in the analog standard linear market."



Bookings Increased in Q3
National's  third quarter  bookings  increased 2 percent  sequentially  from the
second  quarter.  Bookings for analog standard linear products grew 8 percent in
Q3. New orders for amplifiers, interface and power management products grew at a
much higher rate than the overall  company  average.  Bookings for products that
serve wireless handsets also increased in Q3. Regionally,  bookings increased in
Asia Pacific and Europe. Year-to-year,  total company bookings increased by more
than 40 percent over last year's third quarter.  Total company bookings exceeded
billings in Q3 FY06.

Outlook for Q4, Fiscal 2006
Based upon current business conditions,  National anticipates that revenues will
grow 2 to 4 percent  during the fourth  quarter of fiscal 2006.  In this revenue
range, gross margin percentage would also be expected to improve slightly in Q4.

Company Declares Dividend
The Company  today  declared a cash dividend of $0.03 per  outstanding  share of
common  stock.  This  dividend  will be paid April 10, 2006 to  shareholders  of
record at the close of business on March 20, 2006.

Stock Buy-Back Program Update
During the third  quarter,  National  bought back $200  million of common  stock
under a previously  approved  stock  repurchase  program.  The diluted  weighted
average shares outstanding for Q3 fiscal 2006 was 354.6 million shares.

Special Note
This release contains forward-looking  statements dependent on a number of risks
and  uncertainties  pursuant  to the  safe  harbor  provisions  of  the  Private
Securities  Litigation  Reform Act of 1995. These factors  include,  but are not
restricted to, new orders received and shipped during the quarter, the degree of
factory utilization, the sale of inventories at existing prices, and the ramp up
and  sale of new  analog  products.  Other  risk  factors  are  included  in the
Company's  10-K for the year ended May 29, 2005 (see  Outlook  and Risk  Factors
sections of  Management's  Discussion  and Analysis of Financial  Conditions and
Results of Operations) and the 10-Q for the quarter ended November 27, 2005.
