The lower part numbers were established in the s and s, then higher part numbers were added incrementally over decades.
7445 – 7445 BCD to Decimal Decoder/Driver Datasheet
PLA 12 inputs, 50 terms, 6 outputs. 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.
These parts are prefixed with 54 instead of 74 in the part number. PLA 12 inputs, 32 terms, 6 outputs, 4 state registers.
All chips dqtasheet this section have two gates, noted by the “2G” in the part numbers. The original series integrated circuits were made by Texas Instruments with the prefix “SN” to create the name SN74xx.

June Learn how and when to remove this template message. 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.
Some of the manufacturers that make these smaller IC chips are: Views Read Edit View history. See List of series integrated circuits.
All chips in this section have one gate, noted by the “1G” in the part numbers. PLA 12 inputs, 32 terms, 6 outputs.
The following is a list of series digital logic integrated circuits. For more details, refer primarily to the Texas Instruments documentation mentioned in the References section. 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 other projects Wikimedia Commons. All chips in this section have three gates, noted by the “3G” in the part numbers.
Some TTL logic parts were made with an extended military-specification temperature range. 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. Please help to improve this article by introducing more precise citations.
However, different manufacturers will use different prefixes or no lc at all. Digital electronics Electronic design Electronics lists Integrated circuits. The “x” in the part number is a place holder for the logic family name. List of books about series integrated circuits. This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations. All chips in the following sections are available 4 to 12 pin surface mount packages.
Older discontinued parts may be available from a limited number of sellers as new old stock NOSthough some are much harder to find.
IC manufacturers continue to make a core subset of this group, but many of these part numbers are considered obsolete and no longer manufactured. Parts in this section have a pin count of 14 pins or more. In a few instances, such as the andthe same suffix in different families do not have completely equivalent logic functions.
Retrieved from ” https: Articles lacking in-text citations from June All articles lacking in-text citations. From Wikipedia, the free encyclopedia. A short-lived 64 prefix on Texas Instruments parts indicated an industrial temperature range; this prefix had been dropped from the TI literature by AND-gated positive edge triggered J-K flip-flopasynchronous preset and clear.
Conversely, the series has “borrowed” from the series – such as the CD and CD being pin-for-pin functional replacements for 74C and 74C A few alphabetic characters to designate a specific logic subfamily may immediately follow the 74 or 54 in the part number, e.
Surface mount parts with a single gate often in a 5-pin or 6-pin package are prefixed with G instead of 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.
Retrieved July 27, Not all functions are available in all families.
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.
