Lqad preset to binary thirteen. Data in is shown by the solid line for both devices. Data inputs B and C are held at the low logic level. A disadvantage ofdoesn’t apply, because the TC output of a given stage is not affected by its own CE.

All diodes are 1 N or equivalent. Data inputs A and Datasheft are shown by the solid line. Output states in row 11 apply for ddatasheet states in rows 11 through 14DC Characteristics Table. 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. The latter output produces a high-level output pulse with a duration approximately equal to one complete cycle datasheer the clock when the counter overflows or underflows.

Two outputs have been made available to perform the cascading function: Count down to one, zero minimumfifteen, fourteen, and thirteen.

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. Add arrow from 15 to 8.


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. LOAD is active l o w and Load the load data.

A high 74ls10 the enable input inhibits counting. Count up to eight, nine maximumzero, one, and two. Customers are responsible for their products and applications using Tl components.

An asynchronous parallel load input overrides coun ting and loads the data.

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.

Search the history of over billion web pages on the Internet. Tl assumes no liability for applications assistance or customer product design. Table 1 shows the generic functions and Table 2. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards.

Reproduction of this information with alteration is an unfair and deceptive business practice. All four data inputs are shown by the solid line. The input pulses are supplied by generators having the following characteristics: 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 inputs are equipped w ith.

Following are URLs where you can datashest information on other Texas Instruments products and application solutions: Voltage values are with respect to network ground terminal. 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.

When low, the counter count up and when high, it counts down. Datzsheet where mandated by government requirements, testing of all parameters of each product is not necessarily performed.

Conditions on other inputs are irrelevant. 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 count enable input must be low to ensure counting. All data inputs are low.
