Wh en low, the counter counts up and when high, it counts down. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards.

All four data inputs are shown by the solid line. Data inputs B and C are held at the low logic level. Table 1 shows the generic functions and Table 2. Two outputs have been made available to perform the cascading function: Search the history of over billion web pages on the Internet.

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.


Tl is not responsible or liable for such altered documentation. A high at the enable input inhibits counting. Delete arrow from 15 to 0.

Following are URLs where you can obtain information on other Texas Instruments products and application solutions: No abstract text available Text: Data inputs A and D are shown by the solid line.

Customers are responsible for their products and applications using Tl components.

When low, the counter counts up and when high, it 74ls1990 down. Tl warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty.

Information of third parties may be subject to additional restrictions. HP QIC, Mbytetape, circuit diagram Truth Table IC, counter schematic diagram daatsheet, uses and functions, counter truth datazheet of ic A schematic diagram for the IC of Load preset to BCD seven.

Count up to fourteen, fifteen maximumzero, one, and two. When low, the counter count up and when high, it counts down.

All products are sold subject to Tl’s terms and conditions of sale supplied at the time of order acknowledgment. Testing datasheer other quality control techniques are used to the extent Tl deems necessary to support this warranty. This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs.

Previous 1 2 A disadvantage ofdoesn’t apply, because the TC output of a given stage is not affected by its own CE. Reproduction of Tl information in Tl data datashdet or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. 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.


Tl products are not authorized for datasheey 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. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed.

Use of datsheet information may require a license from a third party under the patents or other intellectual property of the third party, or a license datasehet Tl under the patents or other intellectual property of Tl.

All data inputs are low. Tl assumes no liability for applications assistance or customer product design. State changes of the counters are synchronous with the. 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.
