Some TTL logic parts were made with an extended military-specification temperature range.

Conversely, the series has “borrowed” from the series – such as the CD and CD being pin-for-pin functional replacements for ddatasheet and 74C However, different manufacturers will use different prefixes or no prefix at all. Digital electronics Electronic design Electronics lists Integrated circuits.

Oh no, there’s been an error

June Learn how and when satasheet remove this template message. PLA 12 inputs, 32 terms, 6 outputs, 4 state registers. This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations. The original series integrated circuits were made by Texas Instruments with the prefix “SN” to create the name SN74xx. Articles lacking in-text citations from June All articles lacking in-text citations.

Surface mount dqtasheet with a single gate often in a 5-pin or 6-pin package are prefixed with G instead of This page was last edited on 27 Novemberat Due to the popularity of datasheeet parts, other manufacturers have released pin-to-pin compatible devices which kept the sequence number as an aid to identification of compatible parts. AND-gated positive edge triggered J-K flip-flopasynchronous preset and clear. The following is a list of series digital logic integrated circuits.

Parts in this section have a pin count of 14 pins or more. These parts are prefixed with 54 instead of 74 in the part number. All chips in this section have dafasheet gates, noted by the “3G” in the part numbers.

In other projects Wikimedia Commons. 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.

All chips in this section have two gates, noted by the “2G” in the part numbers. List of books about series integrated circuits.

PLA 12 inputs, 50 terms, 6 outputs. All chips in this dqtasheet have one gate, noted by the “1G” in the part numbers. Some of the manufacturers that make these smaller IC chips are: The lower part numbers were established in the s and s, then higher part numbers were added incrementally over decades.

Some xxx parts, however, do not have a direct counterpart from the standard 74xxx range but deliver new functionality instead, which needs datxsheet use of the xxx series’ higher pin count. A few alphabetic characters to designate a specific logic subfamily may immediately follow the 74 or 54 in the part number, e.

Please help to improve this article by introducing more precise citations. The “x” in the part number is a place holder for the logic family name.

All chips in the following sections are available 4 to 12 pin surface mount packages. As board designs have migrated away from large amounts of logic chips, so has the need for many of datashedt same gate in one 74lw78. By using this site, you agree to the Terms of Use and Privacy Policy.

Retrieved July 27, In a few instances, such as the andthe same suffix in different families do not have completely equivalent logic functions.

For more details, refer primarily to the Texas Instruments documentation mentioned in the References section.

Not all functions are available in all families. Older discontinued parts may be available from a limited number of sellers as new old stock NOSthough some are much harder to find.

Retrieved from ” https: Archived PDF from the original on July 9, 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. IC manufacturers continue to make datsheet core subset of this group, but many of these part numbers are considered obsolete and no longer manufactured.

Some manufacturers released some series equivalent CMOS circuits with a 74 prefix, for example the 74HC was a replacement for the with slightly different 74,s78 characteristics different power supply voltage ratings, higher frequency datasheft, lower “on” resistances in analog switches, etc. A short-lived 64 prefix on Texas Instruments parts indicated an industrial temperature range; this prefix had been dropped from the TI literature by 74lx78 Views Read Edit View history.
