Tl is not responsible or liable for such altered documentation.
Voltage values are with respect to network ground terminal. This mode of operation eliminates the output counting spikes normally associated with asyn- chronous ripple clock counters. 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.
Customers are responsible for their products and applications using Tl components. 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.
Buyers represent that they have all necessary dattasheet 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 datasneet their products and any use of Ddatasheet products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by Tl.
All products are sold subject to Tl’s terms and conditions of sale supplied at the time of order acknowledgment. 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. Data inputs A, B, and C are shown by the solid line.
Level changes at the enable input should be made only datasehet the clock in- put is high. For simplication, pulse rise times, reference levels, etc. 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.
Count down to one, zero minimumfifteen, fourteen, and thirteen. Count up to fourteen, fifteen maximumzero, one, and two.

Data inputs A and D are shown by the solid line. 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. Tl warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty. 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.
I qq is measured with all inputs grounded and all outputs open. Production processing does not necessarily include testing of all parameters.
When low, the counter count up and when high, it counts down. Information published by Tl regarding third-party products or services datashheet 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. 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 fatasheet 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. 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. Data inputs B and C are held at the low logic level.
Information of third parties may be subject to additional restrictions. Data input D is shown by the dashed line. The latter output produces datssheet high-level output pulse with a duration approximately equal to one complete cycle of the clock when the counter overflows or underflows.
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. A high at the enable input inhibits counting.

SN54′, SN74′ Circuits 5. Full text of ” IC Datasheet: Two outputs have been made available to perform the cascading function: The input pulses are supplied by generators having the following characteristics: Tl is not responsible or liable for any such statements.
Conditions on other inputs are irrelevant. 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.
