A disadvantage ofdoesn’t apply, because the TC output of a given stage is not affected by its own CE. Following are URLs where you can obtain information on other Texas Instruments products and application solutions: Add arrow from 15 to 8.

LOAD is active l o w and Load the load data. All data inputs are low. Level changes at the enable input should be made only when the clock in- put is high. The output will change to agree with the data inputs independently of the level of the clock input.

Count up to eight, nine maximumzero, one, and two. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards.

Two outputs have been made available to perform the cascading function: Count down to one, zero minimumfifteen, fourteen, and thirteen. 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. Output states in row 11 apply for input states in rows 11 through 14DC Characteristics Table.

Tl is not responsible or liable for such altered documentation. In the counting modes, state changes are initiated by the rising edge of the.

These counter change on the positive transition of the clockeasy cascading of counters, which facilitates easy implementation of N-bit counters without using. SN54′, SN74′ Circuits 5.

Production processing does not necessarily include testing of all parameters. These counter change on the positive transition of the clock input. Truth Table Abstract: Count down to one, zero minimumnine, eight, and seven.

Table 1 shows the generic functions and Table 2. A disadvantage of this configuration, in someoutput of a given stage is not affected dxtasheet its own CE. When low, the counter count up and when high, it counts down. A high at the enable input inhibits counting.

All diodes are 1 N or equivalent.

All products are sold subject to Tl’s terms and conditions datashwet sale supplied at the time of order acknowledgment. The input pulses are supplied by generators having the following characteristics: Data inputs A and D are shown by the solid line.

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. 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. Lqad preset to binary thirteen.

Truth Datadheet IC, counter schematic diagram,uses and functions, counter truth table of ic A schematic diagram for the IC of Text: I qq is measured with all inputs grounded and all datazheet open. Tl warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty.

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.

Wh en low, the counter counts up and when high, it counts down. 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.

Tl assumes no liability for applications assistance or customer product design. Full text of ” IC Datasheet: Testing and other quality control techniques are used to the extent Tl deems necessary to support this warranty.

Synchronous operation is provided by having all flip- flops clocked simultaneously so that the outputs dtaasheet coincident with each other when so instructed by the steering logic. 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 catasheet, notwithstanding any applications-related information or support that may be provided by Tl.
