Please help to improve this article by introducing more precise citations. Datasyeet of the manufacturers that make these smaller IC chips are: In a few instances, such as the andthe same suffix in different families do not have completely equivalent logic functions.

IC manufacturers continue to make a core subset of this group, but many of these part numbers are considered obsolete and no longer manufactured.

Views Read Edit View history. However, different manufacturers will use different prefixes or no prefix at all.
The “x” in the darasheet number is a place holder for the logic family name. A short-lived 64 prefix on Texas Instruments parts indicated an industrial temperature range; this prefix had been dropped from the TI literature by 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.
This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations.
As board designs have migrated away from large amounts of logic chips, so has the need for many of the same gate in one package. All chips in the following sections are available 4 to 12 pin surface mount dayasheet.
Now logic can be placed where it is physically needed on a board, instead of running long signal traces to a full-size logic chip that has many of the same gate. Retrieved from ” https: PLA 12 inputs, 32 terms, 6 outputs.
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. Some TTL logic parts were made with an extended military-specification temperature range.
All chips in this section have three gates, noted by the “3G” in the part numbers.

The following is a list of series digital logic integrated circuits. A few alphabetic characters to designate a specific logic subfamily may immediately follow the 74 or 54 in the part number, e.
Not all functions are available in all families. AND-gated positive edge triggered J-K flip-flopasynchronous preset and clear.

Digital electronics Electronic design Electronics lists Integrated circuits. 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. Parts in this section have a pin count of 14 pins or more.
Some manufacturers released some series equivalent CMOS circuits with a 74 dafasheet, for example the 74HC was a replacement for the with slightly different electrical characteristics different power supply voltage ratings, higher frequency capabilities, lower “on” resistances in analog switches, etc.
