Count down to one, zero minimumfifteen, fourteen, and thirteen.

A high at the enable input inhibits counting. All diodes are 1 N or equivalent. Resale of Tl 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.

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. Information published by Tl regarding third-party products or services does not constitute a license from Tl to use such products or services or a warranty or endorsement thereof.

The ripple clock output produces a low-level output pulse equal in width to the low- level portion of the clock input when dwtasheet overflow or underflow condition exists. I qq is measured with all inputs grounded and all outputs open. Reproduction of this information with alteration is an unfair and deceptive business practice. Search the history of over billion web pages on the Internet.

Data 7190 A and D are shown by the solid line. Two outputs have been made available to perform the cascading function: Data input D is shown by the dashed line. When low, the counter count up and when high, it counts down. Reproduction of Tl information in Tl data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices.

Tl assumes no liability for applications assistance or customer product design. Information of third parties may be subject to additional restrictions.

Data inputs A, B, and C are shown by the solid line. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from Tl under the patents or other intellectual property of Tl. For simplication, pulse rise times, reference levels, etc. Tl is not responsible or liable for any such statements. The latter output produces a high-level output pulse with a duration approximately equal to one datasheett cycle of the clock when the counter overflows or underflows.

Count down to one, zero minimumnine, eight, 774190 seven. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards. Testing and other quality control techniques are used to the extent Tl deems necessary datasyeet support this warranty. Count up to fourteen, fifteen maximumzero, one, and two. All four data inputs are shown by the solid line.

To test Qq output of datwsheet and ‘LS Data inputs B and C are held at the low logic level. All data inputs are low.

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 of the parties have executed an agreement specifically governing such use. Pin numbers shown are for D, J, and N packages.

Tl is not responsible or liable for such datsaheet documentation. This mode of operation eliminates the output counting spikes normally associated with asyn- chronous ripple clock counters. Tl warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty. The output will change to agree with the data inputs independently dztasheet the level of the clock input.

Data in is shown by the solid line for both devices.

Voltage values are with respect to network ground terminal. These counters are fully programmable; that is, the outputs may be preset to either level by placing a low on the load input and entering the desired data at the data inputs.

Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of Tl products in such safety-critical applications, notwithstanding any applications-related information or support 7490 may be provided by Tl.

All products are sold subject to Tl’s terms and conditions of sale supplied at the time of order acknowledgment. Level changes at the enable input should be made only when the clock in- put is high.

Customers are responsible for their products and applications using Tl components. The counters can be easily cascaded by feeding the ripple clock output to the enable input of the succeeding counter if parallel clocking is used, or to the clock input if parallel enabling is used. Conditions on other inputs are irrelevant.

Synchronous operation is provided by having all flip- flops clocked simultaneously so that the outputs change coincident with each other when so instructed by the steering logic. Minimum count enable time is the interval immediately preceeding the rising edge of the clock pulse during which interval the count enable input must be low to ensure counting. 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.

Customers should obtain the latest relevant information before placing orders datasheer should verify that such information is current and complete.

Dataaheet acknowledge and agree that any such use of Tl products which Tl has not designated as military-grade is solely at the Buyer’s risk, and that they are solely responsible for compliance datashfet all legal and regulatory requirements eatasheet connection with such use.

Count up to eight, nine maximumzero, one, and two. Tl does not warrant or represent that any license, either express or implied, is granted under any Tl datashest 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.
