I qq is measured with all inputs grounded and all outputs open. Tl warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty.
Tl assumes no liability for applications assistance or customer product design. Two outputs have been made available to perform the cascading function: This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs. All diodes are 1 N or equivalent. Tl is not responsible or liable for any such statements. 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.
Count down to one, zero minimumfifteen, fourteen, and thirteen. To test Qq output of ‘ and ‘LS Reproduction of this information with alteration is an unfair and deceptive business practice. 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.
Load preset to BCD seven. Tl is not responsible or liable for such altered documentation.

Pin numbers shown are for D, J, and N packages. For simplication, pulse rise times, reference levels, etc. The input pulses are supplied by generators having the following characteristics: Information of third parties vatasheet be subject to additional restrictions.
When low, the counter count up and when high, it counts down. 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.
Data input D is shown by the dashed line. 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, 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.
The output will change to agree with the data inputs independently of the level of the clock input. SN54′, SN74′ Circuits 5.
Information published by Tl regarding third-party products or services does not constitute ratasheet license from Tl to use such products or services or a warranty or endorsement thereof.
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 datasheeet 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.

The latter output produces datashewt high-level output pulse with a duration approximately equal to one complete cycle of the clock when the counter overflows or underflows. 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.
Voltage values are with respect to network ground terminal. 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. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards.
Count down to one, zero minimumnine, eight, and seven. Buyers acknowledge and agree that any such use of Tl products which Tl has not designated as military-grade is solely at the Buyer’s risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with dagasheet use.
The ripple clock output produces a low-level output pulse equal in width to the low- level portion of the clock 744190 when an overflow or underflow condition exists. Data in is shown by the solid line for both devices. These counters are fully programmable; that is, the outputs may be preset to either level datasjeet 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.
This mode of operation eliminates the output counting spikes normally associated with asyn- chronous ripple clock counters. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed. Customers are responsible for their products and applications using Tl components. Count up to eight, nine maximumzero, one, and two. Level changes at the enable input should be made only when the clock in- put is high. 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.
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. Lqad preset to binary thirteen. Production processing does not necessarily include testing of all parameters. 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.
All four data inputs are shown by the solid line. Full text of ” IC Datasheet: Following are URLs where you can obtain information on other Texas Instruments products and application solutions: Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. Conditions on other inputs are irrelevant. Data inputs A, B, and C are shown by the solid line.
