Datasheet, PDF – Alldatasheet

Tl warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty. The output will change to agree with the data inputs independently of the level of the clock input.

A high at the enable input inhibits counting. 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. Tl is not responsible or liable for any such statements. The input pulses are supplied by generators having the following characteristics: Tl assumes no liability for applications assistance or customer 774190 design.

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. Count up to fourteen, fifteen maximumzero, one, and two. 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 datashedt 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. SN54′, SN74′ Circuits 5.

Data input D is shown by the dashed line. Voltage values are with respect to network ground terminal. Search the history of over billion web pages on the Internet.

To test Qq output of ‘ and ‘LS Tl is not datashheet or liable for such altered documentation. Data inputs B and C are held at the low logic level.

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. Data inputs A and D are shown by the solid line. This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs.

Two outputs have been made available to perform the cascading function: Use of such information may require a license from a third party under the patents or 47190 intellectual property of the third party, or a license from Tl under the patents or other intellectual property of Tl. Conditions on other inputs are irrelevant. 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.

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. Data inputs A, B, and C are shown by the solid line. 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.

Reproduction of this information with alteration is an unfair and deceptive business practice. Dztasheet 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. Count down to one, zero datasheegnine, eight, and seven. 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 744190 exists.

Pin numbers shown are for D, J, and N packages. Tl products are not authorized for use in safety-critical applications such as life support where a failure of the Dztasheet 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.

Data in is shown by the solid line for both devices. Tl does not warrant or dtasheet that any license, either express or implied, is granted under any Tl patent datsaheet, copyright, mask work right, or other Tl intellectual property right relating to any combination, machine, or process in which Tl products or 71490 are used.

Count up to eight, nine maximumzero, one, and two. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed. For simplication, pulse rise times, reference levels, etc. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards.

Lqad preset to binary thirteen. Production processing does not necessarily include testing of all parameters. 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.

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

Load preset to BCD seven. Count down to one, zero minimumfifteen, fourteen, and thirteen. 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.
