1、JEDEC STANDARD Unified Wide Power Supply Voltage Range CMOS DC Interface Standard for Non-Terminated Digital Integrated Circuits JESD8-23 OCTOBER 2009 JEDEC SOLID STATE TECHNOLOGY ASSOCIATION NOTICE JEDEC standards and publications contain material that has been prepared, reviewed, and approved thro
2、ugh the JEDEC Board of Directors level and subsequently reviewed and approved by the JEDEC legal counsel. JEDEC standards and publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improve
3、ment of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for use by those other than JEDEC members, whether the standard is to be used either domestically or internationally. JEDEC standards and publications are adopted without regard to whether
4、or not their adoption may involve patents or articles, materials, or processes. By such action JEDEC does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the JEDEC standards or publications. The information included in JEDEC standards and
5、publications represents a sound approach to product specification and application, principally from the solid state device manufacturer viewpoint. Within the JEDEC organization there are procedures whereby a JEDEC standard or publication may be further processed and ultimately become an ANSI standar
6、d. No claims to be in conformance with this standard may be made unless all requirements stated in the standard are met. Inquiries, comments, and suggestions relative to the content of this JEDEC standard or publication should be addressed to JEDEC at the address below, or call (703) 907-7559 or www

10、7559 JEDEC Standard No. 8-23 Page 1 UNIFIED WIDE POWER SUPPLY VOLTAGE RANGE CMOS DC INTERFACE STANDARD FOR NON-TERMINATED DIGITAL INTEGRATED CIRCUITS (From JEDEC Board Ballot JCB-09-50, formulated under the cognizance of the JC-16 Committee on Interface Technology. ) 1 Scope This standard defines DC
11、 interface parameters and test conditions for a family of non-terminated CMOS digital circuits intended for use over a wide power supply voltage range. The standard bridges a number of existing JEDEC standards in the JESD8-x family to facilitate applications that operate over an ultra-wide power sup
12、ply voltage range in order to achieve lower power dissipation or higher performance. Three voltage range categories (1, 2 and 3) are defined to support a variety of application requirements. A design claiming compliance with the standard must specifically identify the category or categories supporte
13、d. This standard specifically does not include interfaces to DDR2 (JESD79-2) or DDR3 (JESD79-3) devices. 2 Standard specification All voltages are referenced to ground except where noted. 2.1 Absolute maximum continuous ratings Parameter Category Range NOTE 1 -0.5 V to 4.6 V 1 2 -0.5 V to 3.6 V 1 Su
