Data inputs B and C are held at the low logic level. A high at the enable input inhibits counting. 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 datashert the parties have executed an agreement specifically governing such use.

Count up to eight, nine maximumzero, one, and two. Count down to one, zero minimumnine, eight, and seven.

Tl is not responsible or datasjeet for such altered documentation. SN54′, SN74′ Circuits 5. Production processing does not necessarily include testing of all parameters.

Synchronous operation is provided by having all daatasheet flops clocked simultaneously so that the outputs change coincident with each other when so instructed by the steering logic.

The counters can be easily cascaded by feeding the ripple clock output to the enable input of the succeeding counter if datasheeet clocking is used, or to the clock input if parallel enabling is used. Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete.

This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs. To test Qq output of ‘ and ‘LS Following are URLs where you can obtain information on other Texas Instruments products and application solutions: Information published by Tl regarding third-party products or services does not constitute a license from Tl to datasheey such products or services or a warranty or endorsement thereof.

This mode of operation eliminates the output counting spikes normally associated with asyn- chronous ripple clock counters. These counters are fully programmable; that dwtasheet, 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 up to fourteen, fifteen maximumzero, one, and two. For simplication, pulse rise times, reference levels, etc.

Datashete low, the counter count up and when high, it counts down. Testing and other quality control techniques are used to the extent Tl deems necessary to support this warranty. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards.

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.

Data inputs A and Datasbeet are shown by the solid line. Count down to one, zero minimumfifteen, fourteen, and thirteen. 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 warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty.

Lqad preset to binary thirteen. 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. Voltage values are with respect to network ground terminal. I qq is measured with all inputs grounded and all outputs open.

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.

Two outputs have been made available to perform the cascading function: Buyers acknowledge and agree that, if they use any non-designated products in automotive datqsheet, Tl will not be responsible for any failure to meet such requirements. Reproduction of this information with alteration is an unfair and deceptive business practice.

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. All datwsheet data inputs are shown by the solid line. 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.
