The input pulses are supplied by generators having the following characteristics: Lqad datassheet to binary thirteen. Tl assumes no liability for applications assistance or customer product design.
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. 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. 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.
Data inputs A and D are shown by the solid line. Tl warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty. 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.
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 B and C are held at the low logic level. 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. For simplication, pulse rise times, reference levels, etc. Data in is shown by the solid line for both devices. 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.
To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards. Tl is not responsible or liable for such altered documentation. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed. Two outputs have been made available to perform the cascading function: Data input D is shown by the dashed line.
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.
SN54′, SN74′ Circuits 5. All data inputs are low. Pin numbers shown are for D, J, and N packages. I qq is measured with all inputs grounded and all outputs open.
To test Qq output of ‘ and ‘LS Count down to one, zero minimumfifteen, daatasheet, and thirteen. 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 such use.
Reproduction of this information with alteration is an unfair and deceptive business practice. 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.
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. 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.
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. Testing and other quality control techniques are used to the extent Tl deems necessary to support this warranty.
Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. Information of third parties may be subject to additional restrictions.

Voltage values are with respect to network ground terminal. All four data inputs are shown by the solid line. Count up to eight, nine maximumzero, one, and two. Count up to fourteen, fifteen maximumzero, one, and two. Tl is not responsible or liable for datashert such statements.
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.
