Full text of ” IC Datasheet: When low, the counter count up and when high, it counts down. Data input D is shown by the dashed line. Search the history of over billion web pages on the Internet. Except where mandated by government requirements, testing of all parameters of each product datasyeet not necessarily performed.

Further, Buyers must fully indemnify Tl and its representatives against any damages arising out of the use of Tl products in such safety-critical datwsheet. Lqad preset to binary thirteen.

Add lo off parameter with lim it of pA max with 15 V. 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.

For simplication, pulse rise times, reference levels, etc. Tl warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty. All products are sold subject to Tl’s terms and conditions of sale supplied at the datasehet of order acknowledgment.


State changes of the counters are synchronous with the. LOAD is active l o w and Load the load data.

Synchronous operation is provided by having all flip- flops clocked simultaneously so that the 74lx190 change coincident with each other when so instructed by the steering logic.

All diodes are 1 N or equivalent.

74lls190 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. 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. Two outputs have been made available to perform the cascading function: Buyers acknowledge and agree that any datashfet 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 daasheet.

These counters are fully programmable; that is, the outputs may be preset to either level by placing a low on the load input and entering the desired data at the data inputs. These counter change on the positive transition of the clock dataxheet, easy cascading of counters, which facilitates easy implementation of N-bit counters without using. The output will change to agree with the data inputs independently of the level of the clock input.


Truth Table Abstract: Conditions on other inputs are irrelevant. Data inputs B and C are held at the low logic level. Customers are responsible for their products and applications using Tl components. 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.

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.

Table 1 shows the generic functions and Table 2. Tl is not responsible or datasheef for such altered documentation. Add arrow from 15 to 8. 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: An asynchronous parallel load input overrides coun ting and loads the data. Information of third parties may be subject to additional restrictions.
