When low, the counter count up and when high, it counts down. Satasheet test Qq output of ‘ and ‘LS Tl assumes no liability for applications assistance or customer product design. I qq is dstasheet with all inputs grounded and all outputs open. 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.

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.

SN54′, SN74′ Circuits 5.

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 vatasheet and any implied warranties for the associated Tl product or service and is an unfair and deceptive business practice.


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.

Count down to one, zero minimumnine, eight, and seven.

Conditions on other inputs are irrelevant. 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.

This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs. All data inputs are low. Production processing does not necessarily include testing of all parameters. Datahseet preset to binary thirteen.

A high at the enable input inhibits counting. Testing and other quality control techniques are used to the extent Tl deems necessary to support this warranty. Full text of ” IC Datasheet: All diodes are 1 N or equivalent.

Customers are responsible for their products and applications using Tl components. The input pulses are supplied by generators having the following characteristics: Data in is shown by the solid line for both devices. All products are sold dayasheet to Tl’s terms and conditions of sale supplied at the time of order acknowledgment.


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. Level changes at the enable input should be made only when the clock in- put is high. Reproduction of this information with alteration is an unfair and deceptive business practice. Tl is not responsible or liable for such altered documentation.

Reproduction of Tl information in Tl data books or data sheets is permissible only if reproduction is without alteration and is accompanied by datasheft associated warranties, conditions, limitations, and notices. All four data inputs are shown by the solid line.

Tl warrants performance of its hardware products to the dataxheet applicable at the time of sale in accordance with Tl’s standard warranty. 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.

Pin numbers shown are for D, J, and N packages. The output will change to agree with the data inputs independently of the level of the clock input.

Two outputs have been made available to perform the cascading function: Data inputs B and C are held at the low logic level. Tl is not responsible or liable for any such statements. Data input D is shown by the dashed line.
