74LS Datasheet –

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.

To test Qq output of ‘ and ‘LS 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. Pin numbers shown are for D, J, and N packages.

When low, the counter count up and when high, it counts down. Load preset to BCD seven. These counter change on the positive transition of the clock input. Following datazheet URLs where you can obtain information on other Texas Instruments products and application solutions: A disadvantage ofdoesn’t apply, because the TC output of a given stage is not affected by its own CE.

Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete.


A disadvantage of this configuration, in someoutput of a given stage is not affected by its own CE.

An asynchronous parallel load input overrides coun ting and loads the data. In the counting modes, state changes are initiated by the rising edge of the. Counting o c cu rs on the positive goin g transition of the clock input. Data input D is shown by the dashed line. 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.

Information of third parties may be subject to additional restrictions. Full text of ” IC Datasheet: All data inputs are low. Voltage values are with respect to network ground terminal. Customers are responsible for their products and applications using Tl components. This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs.

Count down to one, zero minimumnine, eight, and seven. The input pulses are supplied by generators having the following characteristics: Previous 1 2 Testing and other quality control techniques are used to the extent Tl deems necessary to support this warranty.

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

This mode of operation eliminates the output counting spikes normally associated with asyn- dataasheet ripple clock counters. Truth Table IC, counter schematic diagram,uses and functions, counter truth table of ic A schematic diagram for the IC of Text: Tl assumes no liability for applications assistance or customer product design. No abstract text available Text: Production processing does not necessarily include testing of all parameters.


Data in is shown by the solid line for both devices. State changes of the counters are synchronous with the. Tl warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty. 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.

Tl is not responsible or liable for any such statements. All inputs are equipped 74lss190 ith. Tl is not responsible or liable for such altered documentation. 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.

The output will change to agree with the data inputs independently of the level of the clock input. Count down to one, zero minimumfifteen, fourteen, and thirteen. 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.
