Samples may or may not be available. Posted by Mittie B. Tl does not warrant or represent that any license, either express or implied, is granted under any Tl patent right, copyright, mask work right, or other Tl intellectual property right relating to any combination, machine, or process in which Tl products or services are used.

Tl products are not authorized for use in safety-critical applications such as life support where a failure of the Tl product would reasonably be expected to cause severe personal injury or death, unless officers dxtasheet the parties have executed an agreement specifically governing such use.

Following are URLs where you can obtain information on other Texas Instruments products and application solutions: JlOniy one output should be shorted at a time. All products are sold subject to Tl’s terms and conditions of sale supplied at the time of order acknowledgment. End around carry can be accomplish- ed without the need for logic or level inversion.

The adder logic, including the carry, is implemented in Its true form. Further, Buyers must fully indemnify Tl and its representatives against any damages arising out of the use of Tl products in such safety-critical applications. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, Tl will not be responsible for any failure to meet such requirements.


Tl has taken and continues to take reasonable steps to provide representative and accurate information but may not have conducted destructive testing or chemical analysis on incoming materials and chemicals. This capability provides the system designer with partial look-ahead performance at the economy and reduced package count of a ripple-carry implementation. These adders feature full internal look-ahead across all four bits generating the carry term in ten nanoseconds, typically, for the ‘ and ‘LS, and 7.

Resale of Lc products or services with statements different from or beyond the parameters stated by Tl for that product or service voids all express and any implied warranties for the associated Tl product or service and is an unfair and deceptive business practice. Pin nunnbers shown are for D, J, N, and W packages. Tl and Tl suppliers consider certain information to be proprietary, and thus GAS datashest and other limited information may not be available for release.

To minimize the risks associated with customer products and applications, customers should provide adequate design and eatasheet safeguards.

Load circuits and voltage waveforms are shown in Section 1. Tl bases its knowledge and belief on information provided by third parties, and makes no representation or dattasheet as to the accuracy of such information. Device has been announced but is not in production.

Addendum-Page 2 Texas Instruments www. Customers are responsible for their products and applications using Tl components. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed. Product device recommended for new designs. Tl’s terms “Lead-Free” or “Pb-Free” mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.

The datasheeet high performance versions are also functionally identical.

Tl has announced that the device will be discontinued, and a lifetime-buy period is in effect. The sum S outputs are provided for each bit and the resultant carry C4 is obtained from the fourth bit. All of its essential components and connections are illustrated by graphic symbols arranged to describe operations as clearly as possible but without regard to the physical form of the various items, components or connections.

Device is in production to support existing customers, but Tl does not recommend using this part in a new design. The information provided on this page represents Tl’s knowledge and belief as of the date that it is provided.
