All diodes are 1 N or equivalent. SN54′, SN74′ Circuits 5. All data inputs are datashfet. Tl assumes no liability for applications assistance or 741190 product design. Data inputs A, B, and C are shown by the solid line. Count down to one, zero minimumnine, eight, and seven. 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.

The output will change to agree with the data inputs independently of the level of the clock input. Datasheer inputs A and D are shown by the solid line. Pin numbers shown are for D, J, and N packages. Data input D is shown by the dashed line.

To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards.

Information published by Tl regarding third-party products or services does 741900 constitute a license from Tl to use such products or services or a warranty or endorsement thereof.

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. All products are sold subject to Tl’s terms and conditions of sale supplied at the time of order acknowledgment. Voltage values are with respect to network ground terminal. Following are URLs where you can obtain information on other Texas Instruments products and application solutions: 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.

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.

Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete.

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.

Information of third parties may be subject to additional restrictions. Load datasheer to BCD seven. Count up to fourteen, fifteen maximumzero, one, and two. 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. To test Qq output of ‘ and ‘LS 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.

Tl is not responsible or liable for any such statements. All four data inputs are shown by the solid line. 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. Lqad preset to binary thirteen. This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs.

Reproduction of this information with alteration is an unfair and deceptive business practice.

Level changes at the enable input should be made only when the clock in- put is high. Minimum count enable time is the interval immediately preceeding the rising edge of the clock pulse during which interval the datashset enable input must be low to ensure counting. When low, the counter count up and when high, it counts down.

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.

Tl warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty. For simplication, pulse rise times, reference levels, etc. Count down to one, zero minimumfifteen, fourteen, and thirteen.

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.

This mode of operation dataasheet the output counting spikes normally associated with asyn- chronous ripple clock counters. Data inputs B and C are held at the low logic level. Count up to eight, nine maximumzero, one, and two. Two outputs have been made available to perform the cascading function: The input pulses are supplied by generators having the following characteristics: These counters are fully programmable; that is, the outputs may datassheet preset to either level by placing a low on the load input and entering the desired data at the data inputs.

Testing and other quality control techniques are used to the extent Tl deems necessary to support this warranty. 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. Search the history of over billion web pages on the Internet.

Production processing does not necessarily include testing of all parameters. I qq is measured with all inputs grounded and all outputs open.
