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

Pin numbers shown are for D, J, and N packages. 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.

Level changes at the enable input should be made only when the clock in- put is high. Count down to one, zero minimumfifteen, fourteen, and thirteen.

The output will change to agree with the data inputs independently of the level of the clock input. Load preset to BCD seven. Tl is not responsible or liable for such altered documentation.

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 complete cycle of the clock when the counter overflows or underflows. 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. Count down to one, zero minimumnine, eight, and seven. Conditions on other inputs are irrelevant.

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. Voltage values are with respect to network ground terminal.

Minimum count enable time is the interval immediately preceeding the rising datashdet of the clock pulse during which dataheet the count enable input must be low to ensure counting.

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

Count up to eight, nine maximumzero, one, and two. 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 high, it counts down. 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.

Data input D is shown by the dashed line. All products are sold subject to Tl’s terms and conditions of sale supplied at the time of order dtasheet.

All four data inputs are shown by the solid line. Two outputs have been made available to perform the cascading function: Customers should obtain the latest relevant information before placing orders and should verify datasjeet such information is current and complete. Data inputs B and C are held at the low logic level. Data inputs A, B, and C are shown by the solid line. A high at the enable input datasheeg counting. Following are URLs where you can obtain information on other Texas Instruments products and application solutions: 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 of third parties may be subject to additional restrictions. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed. This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset 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 xatasheet 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.

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. Tl warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty. To test Qq output of ‘ and ‘LS 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 assumes no liability for applications assistance or customer product design. Data inputs A and D are shown by the solid line.

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.
