The following is a list of series digital logic integrated circuits. The key dxtasheet returns the authorization identification to the car through ultra high frequency UHF to enable the engine start.

Texas Instruments

When low, the counter count up and when high, it counts down. A high at the enable input inhibits counting. Count up to eight, datasheey maximumzero, one, and two. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards.

Tl is not responsible or liable for any such statements. These parts are prefixed with 54 xatasheet of 74 in the part number. Due to the popularity of these parts, other manufacturers have released pin-to-pin compatible devices which kept the sequence number as an aid to identification of compatible parts.

The lower part numbers were established in the s and s, then higher part numbers were added incrementally over decades. Customers are responsible for their products and applications using Tl components. PLA 12 inputs, 32 terms, 6 outputs, 4 state registers. Surface mount parts with a single gate often in a 5-pin or 6-pin package are prefixed with G instead of Reproduction of Tl information in Tl data books or data sheets is dafasheet only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices.

Voltage values are with respect to network ground terminal. Please help to improve this article by introducing more precise citations. You’ll need to use the load pin pin 11 to load a 5 or what ever number you want to start atinto the counter then have it count down.

For simplication, pulse rise times, reference levels, etc. The output will change to agree with the data inputs independently of the level of the clock input.

NTE – IC-TTL Synchronous Up/Down Decade Counter

June Learn how and datasheeh to remove this template message. Two outputs have been made available to perform the cascading function: A few alphabetic characters to designate a specific logic subfamily may immediately follow the 74 or 54 in the part number, e. Reproduction of this information with alteration is an unfair and deceptive business practice. Advanced and high performance security dztasheet solution that prevents the car engine from running unless the correct key is present.

Conditions on other inputs are irrelevant. Roff Well-Known Member Nov 24, 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.

Some TTL logic parts were made with an extended military-specification temperature range. This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs. SN54′, SN74′ Circuits 5. Contact General inquiries Representatives and distributors Sales contacts Press contacts Investor relations contacts.

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 datasehet and is an unfair and deceptive business practice. See List of series integrated circuits. To test Qq output of ‘ and ‘LS Data inputs A and D are shown by the solid line.

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.
