Exhibit 99.1

IDT ANNOUNCES RESIGNATION OF PETER FELD FROM THE BOARD OF DIRECTORS

SAN JOSE, Calif.-- February 26, 2014 -- Integrated Device Technology, Inc. (IDT®) (NASDAQ: IDTI), the Analog and Digital Company™ delivering essential mixed-signal semiconductor solutions, today announced that Peter Feld has resigned as a member of the company’s board of directors, effective February 26, 2014. Feld served on IDT’s board since June 2012.

“I want to thank Peter for his service on the board for the last twenty months,” said John Schofield, IDT’s chairman of the board. “Peter brought a fresh perspective and helped the board attain a higher level of performance. He has significantly helped the board and the Company to enhance shareholder value with his professionalism and contributions. I have valued his counsel during his tenure on the Board of Directors.”

Greg Waters, IDT’s president and CEO, stated, “It has been a pleasure working with Peter throughout the CEO search process and since my appointment as CEO. We share a common goal of creating value for the benefit of all IDT shareholders and are aligned on the Company’s go-forward strategy.”

Since June 2012, operating margins have improved from low single digits to over 20 percent last quarter, and the stock price is currently at a six-year high. IDT is extremely well positioned for future success with a renewed product focus, best-in-class financial performance, a healthy balance sheet and a very talented employee base. I would like to thank my fellow board members for the opportunity to serve as a director for IDT. I look forward to remaining a shareholder as the Company continues to execute.”
