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. The following is a list of series digital logic integrated circuits.

From Wikipedia, the free encyclopedia. Some TTL logic parts were made with an extended military-specification temperature range. A few alphabetic characters to designate a specific datasheef subfamily may immediately follow dataasheet 74 or 54 in the part number, e. Some of the manufacturers that make these smaller IC chips are: See List of series integrated circuits.

This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations.

IC manufacturers continue to make a core subset of adtasheet group, but many of these part numbers are considered obsolete and no longer manufactured. For more details, refer primarily to the Texas Instruments documentation mentioned in the References section.

In other projects Wikimedia Commons. Retrieved from 7454 https: All chips in this section have three gates, noted by the “3G” in the part numbers. The lower part numbers were established in the s and s, then higher part numbers were added incrementally over decades.

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.

National Semiconductor

The original series integrated circuits were made by Texas Instruments with the prefix “SN” to create the name SN74xx. As board eatasheet 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 this section have two gates, noted by the “2G” in the part numbers.

Retrieved July 27, List of books about series integrated circuits. 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.

Older discontinued parts may be available from a limited number of sellers as new old stock NOSthough some are much harder to find. A short-lived 64 prefix on Texas Instruments parts indicated an industrial temperature range; this prefix had been dropped from the TI literature by Parts in this section have a pin count of 14 pins or more.

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. 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.
