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. Tl assumes no liability for applications 74os190 or customer product design. Customers are responsible for their products and applications using Tl components.

I qq is measured with all inputs grounded and all outputs open.

Use of such information may require a license from a third party under the patents or other intellectual datasheef of the third party, or a license from Tl under the patents or other intellectual property of Tl.

All inputs are equipped w ith. Data inputs A and D are shown by the solid line.

An asynchronous parallel load input overrides coun ting and loads the data. Output states in row 11 apply for input states in rows 11 through 14DC Characteristics Table.

Delete arrow from 15 to 0. The output will change to agree with the data inputs independently of the level of the clock input. Table 1 shows the generic functions and Table 2.


Search the history of over billion web pages on the Internet. 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. Count down to one, zero minimumnine, eight, and seven. Production processing does not necessarily include testing of all parameters. Conditions on other inputs are irrelevant.

Add lo off parameter with lim it of pA max with 15 V. 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. Lqad preset to binary thirteen. No abstract text available Text: Load preset to BCD seven. Tl warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty.

Truth Table Abstract: Following are URLs where you can obtain information on other Texas Instruments products and application solutions: Pin numbers shown are for D, J, and N packages. Level changes at the enable input should be made only when the clock in- put is high. 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.


A disadvantage ofdoesn’t apply, because the TC output of a given stage is not affected by its own CE. These counters are fully programmable; that is, 74ls109 outputs may be preset to either level by placing a low on the load input and entering the desired data at the data inputs.

Tl is not eatasheet or liable for any such statements. Reproduction of this information with alteration is an unfair and deceptive business practice.

LOAD is active l o w and Load the load data. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed.

Data input D is shown by 74lss190 dashed line.

Add arrow from 15 to 8. When low, the counter counts up and when high, it counts down. Count up to fourteen, fifteen maximumzero, one, and two. Count down to one, zero minimumfifteen, fourteen, and thirteen.
