South Portland, ME 04106


Gentlemen and Ladies:

As the General Counsel to Fairchild Semiconductor International, Inc., a
Delaware corporation (the "Company"), I am familiar with the registration
statement on Form S-8 being filed today by the Company with the Securities and
Exchange Commission relating to 3,873,664 shares (the "Shares") of the
Company's Class A Common Stock to be issued pursuant to and in accordance with
the Fairchild Semiconductor International, Inc. 2000 Stock Option Plan (the
"Plan").

It is my opinion that the Shares, when issued and sold hereafter in accordance
with the provisions of the Plan, in accordance with Delaware law and upon
payment of the exercise price for the Shares as contemplated by the Plan and
option agreements entered into under the Plan, will be validly issued, fully
paid and nonassessable.

I hereby consent to the use of this opinion as Exhibit 5 of the above-referenced
registration statement.

Yours truly,

/s/ Daniel E. Boxer

Executive Vice President,
Chief Administrative Officer,
General Counsel and Secretary
