National Semiconductor Reports $80 Million Profit,
50.6% Gross Margin for Second Quarter Fiscal 2005

  o  Q2 revenues were $448.9 million, down 18% from Q1 and 5% from Q2FY04
  o  GAAP earnings are 21 cents per share, up from 17 cents a year ago
  o  Q2 earnings included 3 cents per share in special gains and credits
  o  Revenue outlook for Q3 of fiscal 2005 is flat to slightly down

SANTA CLARA, CALIF., December 9, 2004 - National Semiconductor Corporation
(NYSE:NSM) today reported a GAAP profit of $80 million, or 21 cents per share,
on revenues of $448.9 million for the second quarter of fiscal 2005, which
ended November 28, 2004. National's second quarter 2005 results included $8.8
million in a special gain from the sale of assets and a $4.2 million benefit
from the resolution of a tax matter. Without these two items, National's Q2
earnings would have been approximately 18 cents per share.

National's second quarter sales were 5 percent lower than Q2 of fiscal 2004,
when the Company reported sales of $473.5 million and earnings of 17 cents per
share. (Historical per share amounts have been adjusted for the Company's
2-for-1 stock split that occurred in May 2004.) Sequentially, National's Q2
revenues decreased 18 percent from the Q1 revenues of $548 million, which
generated earnings of 31 cents per share.

Second quarter gross margin was 50.6 percent, down from 55 percent in the first
quarter, but higher than the 50.1 percent recorded in last year's second
quarter. The sequentially lower gross margin was primarily due to reduced
production volume as the Company lowered its fab capacity utilization percentage
from the mid-90s to the mid-60s.

"Obviously, revenues fell significantly in Q2 as we dealt with ongoing inventory
reductions in the distribution channel," said Brian L. Halla, National's
chairman, president and CEO. "But with our focus on higher-value analog products
and by controlling costs, we were able to keep gross margins above 50 percent
in Q2. I am also pleased that, even with lower year-over-year revenues, we were
able to increase earnings per share. This reinforces that our business model is
working."

Bookings Declined in Q2

National's Q2 worldwide bookings declined 16 percent from Q1 and 31 percent
compared to last year's fiscal second quarter. Orders decreased broadly across
National's varied product lines as distributors and OEM customers continued
their efforts to reduce inventory levels and adjust backlog heading into the
post-holiday period. In particular, the Company experienced slower order rates
from various Asian wireless handset customers and flat-panel display customers.
However, orders for portable power management products were the most positive
development with over 25 percent growth year-to-year and flat sequentially.
This year-to-year growth was driven primarily by portable power management
applications such as mobile phone handsets, MP3 players and game systems. Total
Company billings exceeded bookings in Q2.

Outlook for Q3, FY2005
National Semiconductor anticipates Q3 revenues to be flat or slightly down
compared to Q2 levels. Gross margin percentage is anticipated to be similar to
Q2's gross margin.

"Most of the inventory reductions in the distribution channel are behind us,"
Halla said. "That, combined with the typical seasonality we see from our major
OEM customers, is why we are guiding that third-quarter revenues will be flat
to slightly down from the second quarter."

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 of recently introduced products. Other risk factors are included in
the Company's 10-K for the year ended May 30, 2004 (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 August 29, 2004.
