[2] use the measurement data given for a rough estimation of the r th(j-a) in your application. the actual r th(j-a) value can vary in applications using different layer stacks and layouts. table 5. limiting values in accordance with the absolute maximum rating system (iec 60134). voltages are referenced to gnd (ground = 0 v). symbol parameter conditions min max unit v in voltage on pin in 4 ms transient ? 0.5 +6.0 v p tot total power dissipation [1] -4 0 0m w t stg storage temperature ? 55 +150 ?c t j junction temperature ? 40 +125 ?c t amb ambient temperature ? 40 +85 ?c v esd electrostatic discharge voltage human body model level 6 [2] - ? 6kv machine model class 3 [3] - ? 400 v table 6. operating conditions voltages are referenced to gnd (ground = 0 v). symbol parameter conditions min typ max unit t amb ambient temperature ? 40 - +85 ?c t j junction temperature - - +125 ?c pin in v in voltage on pin in 2.3 - 5.5 v pin en v en voltage on pin en 0 - v in v pin out c l(ext) external load capacitance [1] 0.7 1.0 - ? f table 7. thermal characteristics symbol parameter conditions typ unit r th(j-a) thermal resistance from junction to ambient [1] [2] 250 k/w www.datasheet.net/ datasheet pdf - http://www..co.kr/

information in this document is believed to be accurate and reliable. however, nxp semiconductors does not give any representations or warranties, expressed or implied, as to the accuracy or completeness of such information and shall have no liability for the consequences of use of such info rmation. nxp semiconductors takes no responsibility for the content in this document if provided by an information source outside of nxp semiconductors. in no event shall nxp semiconductors be liable for any indirect, incidental, punitive, special or consequential damages (including - without limitation - lost profits, lost savings, business interruption, costs related to the removal or replacement of any products or rework charges) whether or not such damages are based on tort (including negligence), warranty, breach of contract or any other legal theory. notwithstanding any damages that customer might incur for any reason whatsoever, nxp semiconductors? aggregate and cumulative liability towards customer for the products described herein shall be limited in accordance with the terms and conditions of commercial sale of nxp semiconductors. right to make changes ? nxp semiconductors reserves the right to make changes to information published in this document, including without limitation specifications and product descriptions, at any time and without notice. this document supersedes and replaces all information supplied prior to the publication hereof. suitability for use ? nxp semiconductors products are not designed, authorized or warranted to be suitable for use in life support, life-critical or safety-critical systems or equipment, nor in applications where failure or malfunction of an nxp semiconductors product can reasonably be expected to result in personal injury, death or severe property or environmental damage. nxp semiconductors and its suppliers accept no liability for inclusion and/or use of nxp semiconducto rs products in such equipment or applications and therefore such inclusion and/or use is at the customer?s own risk. applications ? applications that are described herein for any of these products are for illustrative purpos es only. nxp semiconductors makes no representation or warranty that such applications will be suitable for the specified use without further testing or modification. customers are responsible for the design and operation of their applications and products using nxp semiconductors products, and nxp semiconductors accepts no liability for any assistance with applications or customer product design. it is customer?s sole responsibility to determine whether the nxp semiconductors product is suitable and fit for the customer?s applications and products planned, as well as fo r the planned application and use of customer?s third party customer(s). customers should provide appropriate design and operating safeguards to minimize the risks associated with their applications and products. nxp semiconductors does not accept any liability related to any default, damage, costs or problem which is based on any weakness or default in the customer?s applications or products, or the application or use by customer?s third party customer(s). customer is responsible for doing all necessary testing for the customer?s applic ations and products using nxp semiconductors products in order to av oid a default of the applications and the products or of the application or use by customer?s third party customer(s). nxp does not accept any liability in this respect. limiting values ? stress above one or more limiting values (as defined in the absolute maximum ratings system of iec 60134) will cause permanent damage to the device. limiting values are stress ratings only and (proper) operation of the device at these or any other conditions above those given in the recommended operating conditions section (if present) or the characteristics sections of this document is not warranted. constant or repeated exposure to limiting values will permanently and irreversibly affect the quality and reliability of the device. terms and conditions of commercial sale ? nxp semiconductors products are sold subject to the gener al terms and conditions of commercial sale, as published at http://www.nxp.com/profile/terms , unless otherwise agreed in a valid written individual agreement. in case an individual agreement is concluded only the terms and conditions of the respective agreement shall apply. nxp semiconductors hereby expressly objects to applying the customer?s general terms and conditions with regard to the purchase of nxp semiconducto rs products by customer. no offer to sell or license ? nothing in this document may be interpreted or construed as an offer to sell products t hat is open for acceptance or the grant, conveyance or implication of any lic ense under any copyrights, patents or other industrial or intellectual property rights. document status [1] [2] product status [3] definition objective [short] data sheet development this document contains data from the objecti ve specification for product development. preliminary [short] data sheet qualification this document contains data from the preliminary specification. product [short] data sheet production this document contains the product specification. www.datasheet.net/ datasheet pdf - http://www..co.kr/
