These counter change on the positive transition of the clock input. Level changes at the enable input should be made only when the clock in- put is high. 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.

Add lo off parameter with lim it of pA max with 15 V. Tl is not responsible or liable for any such statements. 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. 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.

An asynchronous parallel load input overrides coun ting and loads the data. Data in is shown by the solid line for both devices. All inputs are equipped w ith. Load preset to BCD seven. To test Qq output of ‘ and ‘LS The 47ls190 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.


Following are URLs where you datashset obtain information on other Texas Instruments products and application solutions: Table 1 shows the generic functions and Table 2.

Data inputs A, B, and C are shown by the solid line. Count down to one, zero minimumfifteen, fourteen, and thirteen. No abstract text available Text: The output will change to agree with the data inputs independently of the level of the clock input. 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.

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.

Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. Count up to fourteen, fifteen maximumzero, one, and two. Production datassheet does not necessarily include testing of all parameters. Previous 1 2 Reproduction of this information with alteration is an unfair 74ld190 deceptive business practice. Counting o c cu rs on the positive goin g transition of the clock input.


Buyers acknowledge and 74ls1190 that, if they use any non-designated products in automotive applications, Tl will not be responsible for any failure to meet such requirements. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards.

Errors in Truth Table. Two outputs have been made available to perform the cascading function: All products are sold subject to Tl’s terms and conditions of sale supplied at the time of order acknowledgment.

Full text of ” IC Datasheet: I qq is measured with all inputs grounded and all outputs open. All diodes are 1 N or equivalent. This mode of operation eliminates the output counting spikes normally associated with asyn- chronous ripple clock counters.

Data inputs B and C are held at the low logic level.

Conditions on other inputs are irrelevant. 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. Truth Table Abstract: Data inputs A and D are shown by the solid line.

Customers are responsible for their products and applications using Tl components.
