Buyers 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 with all legal and regulatory requirements in connection with such use. Data in is shown by the solid line for both devices. This mode of operation eliminates the output counting spikes normally associated with asyn- chronous ripple clock counters.

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.

Voltage values are with respect to network ground terminal. Tl warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty. Data input D is shown by the dashed line. The ripple clock output produces a low-level output pulse equal in width to the low- level portion of the clock input when an overflow or underflow condition exists.

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.

All four data inputs are shown by the solid line. 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 are responsible for their products and applications using Tl components.

Level changes at the enable input should be made only when the clock in- put is high.

Following are URLs where you can obtain information on other Texas Instruments products and application solutions: The output will change to agree with the data inputs independently of the level of the clock input.

The latter output produces a high-level output pulse with a duration approximately equal to one complete cycle of the clock when the counter overflows or underflows.

Testing and other quality control techniques are used to the extent Tl deems necessary to support this warranty. The input pulses are supplied by generators having the following characteristics: 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.

All data inputs are low. Tl is not responsible or liable for any such statements. Tl assumes no liability for applications assistance or customer product design. Data inputs A and D are shown by the solid line.

Search the history of over billion web pages on the Internet. All products are sold subject to Tl’s terms and conditions of sale supplied at the time of 774190 acknowledgment.

Datazheet down to one, zero minimumfifteen, fourteen, and thirteen. 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. Lqad preset to binary thirteen. Two outputs have been made available to perform the cascading function: Production processing does not necessarily include testing of all parameters.

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.

To test Qq output of ‘ and ‘LS Data inputs B and C are held at the low logic level. Tl is not responsible or liable for such altered documentation. Count up to eight, nine maximumzero, one, and two.

Use of such information may require a datadheet 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.

Load preset to BCD seven.

Conditions on other 71490 are irrelevant. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards.

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

This datasneet allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs. Pin numbers shown are for D, J, and N packages. A high at the enable input inhibits counting. When low, the counter count up and when high, it counts down. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed.
