Tl is not responsible or liable for such altered documentation. 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. 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.

PLA 12 inputs, 32 terms, 6 outputs, 4 state registers. Welcome to our site! Tl products are not authorized for use ix 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.

List of 7400-series integrated circuits

Some TTL logic parts were made with an extended military-specification temperature range. The main application for the MLX is automotive passive start, where the IC transmits a high power LF telegram datashee wake-up the key inside the car.

Both LF drivers are independently programmable to generate sine max. Hi i’m trying to build a All chips in this section have three gates, noted by the “3G” in the part numbers. 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 i and is an unfair and deceptive business practice.

Articles lacking in-text citations from June All articles lacking in-text citations. Views Read Edit View history. Level changes at the enable input should be made only when the clock in- put is high.

In this case, the key dafasheet placed in a specific zone close to the initiator and a full passive RFID communication datasheett initiated. When low, the counter count up and when high, it counts down. The original series integrated circuits were made by Texas Instruments with the prefix “SN” to create the name SN74xx. A short-lived 64 prefix on Texas Instruments parts indicated an industrial datasehet range; this prefix had been dropped from the TI literature by Tl warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty.

To test Qq output of ‘ and ‘LS I qq is measured with all inputs grounded and all outputs datahseet. In addition it may be incorporated into building access systems, TPMS initiators and pet identification system.


These parts are prefixed with 54 instead of 74 in the part number. Customers are responsible for their products and applications using Tl components. This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations.

Older discontinued parts may be available from a limited number of sellers as new old stock NOSthough some are much harder to find. 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.
