This feature allows the counters to be used as modulo-N dividers by simply modifying the count length datawheet the preset inputs. 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.

Count down to one, zero minimumnine, eight, and seven. To test Qq output of ‘ and ‘LS Tl assumes no liability for applications assistance or customer product design. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards. Buyers acknowledge and agree that, if they dataseet 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 and should verify that such information is current and complete. Data inputs B and C are held at the low logic level.

Tl does not warrant or represent that any license, either express or implied, datashet granted under any Tl patent right, copyright, mask work right, or other Tl intellectual property right relating to any combination, machine, datzsheet process in which Tl products or services are used. 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.

Count down to one, zero minimumfifteen, fourteen, and thirteen. Data inputs A, B, and C catasheet shown by the solid line. Data input D is shown by the dashed line.


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. Use of such information may dqtasheet a license from a third party under the patents or other intellectual property of the third party, or a license from Tl under datasheet patents or other intellectual property of Tl.

The ripple clock output produces a low-level output pulse equal in width to the low- level dztasheet of the clock input when an overflow or underflow condition exists. For simplication, pulse rise times, reference levels, etc. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed.

Customers are responsible for their datasheer and applications using Tl components. 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 that may be provided by Tl.

Conditions on other inputs are irrelevant. 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 order acknowledgment. Load preset to BCD seven. 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: All four data inputs are shown by the solid line. All data inputs are low. Voltage values are with respect to network ground terminal. 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.

Count up to eight, nine maximumzero, one, and two. Following are URLs where you can obtain information on other Texas Instruments products and application solutions: This mode of operation eliminates the output counting spikes normally associated with asyn- chronous ripple clock counters.


When low, the counter count up and when eatasheet, it counts down. Pin numbers shown are for D, J, and N packages. 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.

Count up to fourteen, fifteen maximumzero, one, and two. Information of third parties may be subject to additional restrictions. Tl warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty.

I qq is measured with all inputs grounded and all outputs open. 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.

Reproduction of this information with alteration is an unfair and deceptive business practice. Production processing does not necessarily include testing of all parameters. Two outputs have been made available to perform the cascading function: The output will change to agree with the data inputs independently of the level of the clock input.

SN54′, SN74′ Circuits 5. Data in is shown by the solid line for both devices. 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.

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. 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.
