This page was last edited on 27 Novemberat A few alphabetic characters to designate a specific logic subfamily may immediately follow the 74 or 54 in the part number, e. For more details, refer primarily to the Texas Instruments documentation mentioned in the References section.

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

Some of the manufacturers that make these smaller IC chips are: All chips in this section have one gate, noted by the “1G” in the part numbers. Views Read Edit View history.

National Semiconductor

Some manufacturers released some series equivalent CMOS circuits with a 74 prefix, 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. Retrieved from ” https: Older discontinued parts may be available from a limited number of sellers as new old stock NOSthough some are much harder to find.

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

PLA 12 inputs, 32 terms, 6 outputs, 4 state registers. However, different manufacturers will use different prefixes or no prefix at all.

Surface mount parts with a single gate often in a 5-pin or 6-pin package are prefixed with G instead of Please help to improve this article by introducing more precise citations.

This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations. The “x” in the part number is a place holder for the logic family name.

Due to the popularity of these parts, other manufacturers have released 745 compatible devices which kept the sequence number as datasheer aid to identification of compatible parts. 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.

In a few instances, such as the dataxheetthe same suffix in different families do not have completely equivalent logic functions. A short-lived 64 prefix on Texas Instruments parts indicated an industrial temperature range; this prefix had ix dropped from the TI literature by Some TTL logic parts were made with an extended military-specification temperature range. See List of series integrated circuits.

All chips in this section have three gates, noted by the “3G” in the part numbers. These parts are prefixed with 54 instead of 74 in the part number. June Learn how and when to remove this template message.

Articles lacking in-text citations from June All articles lacking in-text citations. All chips in this section have two gates, noted by the “2G” in the part numbers. By using this site, you agree to the Terms of Use and Privacy Policy.

AND-gated positive edge triggered J-K flip-flopasynchronous preset and clear.

In other projects Wikimedia Commons. The following is a list of series digital logic integrated circuits. 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.

From Wikipedia, the free encyclopedia.

Retrieved July 27, All chips in the following datashheet are available 4 to 12 pin surface mount packages. 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. Archived PDF from the original on July 9, Digital electronics Electronic design Electronics lists Integrated circuits.

The original series integrated circuits were made by Texas Instruments with the prefix “SN” to create the name SN74xx. Conversely, the series has “borrowed” from the series – such as the CD and CD being pin-for-pin functional replacements for 74C and 74C Not all functions are available in all families.

Parts in this section have a pin count of 14 pins or more. 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. PLA 12 inputs, 32 terms, 6 outputs. PLA 12 inputs, 50 terms, 6 outputs.
