Item 5:           Other Events

                  Adoption of Stockholder Rights Plan.

                  On December 20,  1998,  the prior  stockholder  rights plan of
Integrated  Device  Technology,  Inc.  ("IDT"),  which had a ten year  duration,
expired  according to its terms. The IDT Board of Directors adopted a new rights
plan,  effective  as of  December  21,  1998,  and  declared a  dividend  of one
preferred  share  purchase  right (a "Right") for each share of IDT common stock
outstanding on January 4, 1999 (the "Record Date"). In addition,  one Right will
be issued  with each share of IDT  common  stock that  becomes  outstanding  (i)
between the Record Date and the earliest of the Distribution Date (as defined in
the Rights Agreement),  the date the Rights are redeemed and the date the Rights
expire or (ii) following the Distribution  Date and prior to the date the Rights
are redeemed or the date the Rights expire, pursuant to the exercise of employee
stock options or upon the exercise,  conversion or exchange of other  securities
of  IDT  (including  its  5  1/2%  Convertible   Subordinated  Notes  due  2002)
outstanding  before the  Distribution  Date.  Each Right entitles its registered
holder to purchase from IDT one  one-hundredth of a share of IDT Series A Junior
Participating Preferred Stock (the "Preferred Shares") at a price of $45 per one
one-hundredth of a Preferred  Share. A complete  description of the terms of the
Rights are set forth in a Rights Agreement (the "Rights  Agreement") between IDT
and  BankBoston,  N.A.  as Rights  Agent.  A summary  of the  Rights  and Rights
Agreement is included as Exhibit C to the Rights Agreement, which is included as
Exhibit 4.1 hereto.

                  Amendment of Bylaws

                  Effective as of December  21, 1998,  the Board of Directors of
IDT amended and  restated  IDT's Bylaws to: (i) require  stockholders  proposing
actions by written  consent to request that the Board set a record date for such
consent and require advance notice of stockholder  nominations for directors and
proposals  at meetings of IDT's  stockholders;  and (ii) require the vote of the
holders of a majority of the  outstanding  stock of IDT for an  amendment of the
Bylaws by IDT's stockholders.
