Data inputs A, B, and C are shown by the solid line.

Truth Table Abstract: All data inputs are low. Conditions on other inputs are irrelevant.

A disadvantage ofdoesn’t apply, because the TC output of a given stage is not affected by its own CE. Tl is not responsible or liable for such altered documentation. No abstract dataxheet available Text: An asynchronous parallel load input overrides coun ting and loads the data. Add lo off parameter with lim it of pA max with 15 V.

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. Following are URLs where you can obtain information on other Texas Instruments products and application solutions: Two outputs have been made available to perform the cascading function: HP QIC, Mbytetape, circuit diagram Truth Table IC, counter schematic diagram,uses and functions, counter truth table of ic A schematic diagram for the IC of Voltage values are with respect to network ground terminal.


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.

All inputs are equipped w ith. 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 datasehet by Dqtasheet.

The input pulses are supplied by generators having the following characteristics: Full text of ” IC Datasheet: 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. Lqad preset to binary thirteen. Previous 1 2 SN54′, SN74′ Circuits 5.

Count up to eight, nine maximumzero, one, and two. 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 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.


All diodes are 1 N or equivalent.

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.

Count down to one, zero minimumnine, eight, and seven. Errors in Truth Table. 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. Search the history of over billion web pages on the Internet. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed.

This mode of operation eliminates the output counting spikes normally associated with asyn- chronous ripple clock counters.

To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards. This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs.
