All data inputs are low. 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. Information of third parties may be subject to xatasheet restrictions. High i drivers 2. Count up to eight, nine maximumzero, one, and two.

Some xxx parts, however, do not have a direct counterpart from the standard 74xxx range but deliver new functionality instead, which needs making use of the xxx series’ higher pin count. Now logic can be placed where it is physically needed on a board, instead of running long signal traces to a datasheeh logic chip that has many of the same if.

Hi i’m trying to build a I think my wording is correct, it’s been awhile since my intro to digital design class.

Join our mailing list. Full or half bridge capabilities. Data inputs A, B, and C are shown by the solid line. The two drivers can be used in full or half bridge configuration and are protected against overload overcurrent and overtemperature.


Pin numbers shown are for D, J, and N packages. Another extension to the series is the xxx variant, representing mostly the bit wide counterpart of otherwise 8-bit-wide “base” chips with the same three ending digits.

To test Qq output of ‘ and ‘LS Output power programmable from 0. PLA 12 inputs, 32 terms, 6 outputs, 4 state registers. 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. Surface mount parts with a single gate often in a 5-pin or 6-pin package are prefixed with G instead of For more details, refer primarily to the Texas Instruments documentation mentioned in the References section.

Views Read Edit View history. For simplication, pulse rise times, reference levels, etc. When low, the counter count up and when high, it counts down. 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. Older discontinued parts may be available from a limited number of sellers as new old stock NOSthough some are much harder to find.

Conversely, the series has “borrowed” from the series – such as the CD and CD being pin-for-pin functional replacements for 74C and 74C All chips in this section have three gates, noted by the “3G” in the part numbers. In this case, the key is placed in a specific zone close to the initiator and a full passive RFID communication is initiated. Tl is not responsible or liable for any such statements. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Production processing does not necessarily include testing of all parameters.


All four data inputs are shown by the solid line. Articles lacking in-text citations from June All articles lacking in-text citations. Forums New posts Search forums.

List of 7400-series integrated circuits

The lower part numbers were established in the s dagasheet s, then higher part numbers were added incrementally over decades. 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 47190.

Please help to improve this article by introducing more precise citations. 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 datasheet safety-critical applications, notwithstanding any applications-related information or support that may be provided by Tl.
