PRODUCT/PROCESS CHANGE NOTIFICATION Generic Copy 26-JUN-2001 SUBJECT: Product/Process Change Notification #11508 TITLE: Final Notification for MC33067/MC34067 Frequencies "Error Amp Output" EFFECTIVE DATE: 22-Aug-2001 AFFECTED CHANGE CATEGORY: Test Process AFFECTED PRODUCT DIVISION: Analog Products Div ADDITIONAL RELIABILITY DATA: Available Contact your local ON Semiconductor Sales Office or Don Warring <[email protected] > SAMPLES: Contact Below Contact your local ON Semiconductor Sales Office or Laurent Jenck <[email protected]> FOR ANY QUESTIONS CONCERNING THIS NOTIFICATION: Contact Sales Office or Patrick Gandol <[email protected]> DISCLAIMER: Initial Product/Process Change Notification (IPCN) - First Notification distributed to customers. Distributed at least 120 days from the effective date of the change. Final Product/Process Change Notification (FPCN) - Final Notification completing the notification process. Distributed at least 60 days from the effective date of the change. ON Semiconductor will consider this change approved unless specific conditions of acceptance are provided in writing within 30 days of receipt of this notice. To do so, contact your local ON Semiconductor Sales Office. DESCRIPTION AND PURPOSE: The purpose of this PCN is to communicate datasheet limits change. The frequency limits "Error Amp Output low and high" are removed at Ta = +25DegC. The frequency limits "Error Amp Output low and high" on the total variation (temperature and power supply voltage) remain the same.

Error Amp Output high: T#33 at Vcc = 10V from low to High temp. : QA limits: 1850 to 2200 KHz; T#31 at Vcc = 12V at room temp. : QA limits: 1900 to 2150 KHz; T#35 at Vcc = 18V from low to High temp. : QA limits: 1850 to 2200 KHz. New: Error Amp Output low: from Vcc = 10V to 18V; from low to High temp. the QA limits: 490 to 550 KHz; Error Amp Output high: from Vcc = 10V to 18V; from low to High temp. The QA limits: 1850 to 2200 KHz; AFFECTED DEVICE LIST (WITHOUT SPECIALS) PART MC33067DW MC33067DWR2 MC33067P MC34067DW MC34067DWR2 MC34067P Issue Date: 26 Jun, 2001 Page 2 of 2
