| − | {{ | + | The following is a '''list of 7400-series digital logic integrated circuits'''. In the mid-1960s, the original [[7400-series integrated circuits|7400-series]] [[integrated circuit]]s were introduced by [[Texas Instruments]] with the prefix "SN" to create the name SN74xx. Due to the popularity of these parts, other manufacturers released pin-to-pin compatible [[logic gate|logic]] devices and kept the 7400 sequence number as an aid to identification of compatible parts. However, other manufacturers use different prefixes and suffixes on their part numbers. |

| + | A short-lived '''64''' prefix on Texas Instruments parts indicated an industrial temperature range; this prefix had been dropped from the TI literature by 1973. Most recent 7400-series parts are fabricated in [[CMOS]] or [[BiCMOS]] technology rather than TTL. Surface-mount parts with a single gate (often in a 5-pin or 6-pin package) are prefixed with '''741G''' instead of '''74'''. | ||
| − | + | Some manufacturers released some [[4000-series integrated circuits|4000-series]] equivalent CMOS circuits with a 74 prefix, for example, the 74HC4066<ref>{{cite web |title=RCA Solid State Databook High Speed CMOS Logic (1988, page 536) |url=https://archive.org/details/bitsavers_rcadataBooMOS_35821859/page/n536 |publisher= [[RCA]] |access-date=January 14, 2020}}</ref> was a replacement for the 4066 with slightly different electrical characteristics (different power-supply voltage ratings, higher frequency capabilities, lower "on" resistances in analog switches, etc.). See [[List of 4000-series integrated circuits]]. | |
| − | + | Conversely, the 4000-series has "borrowed" from the 7400 series{{snd}} such as the CD40193 and CD40161 being pin-for-pin ''functional'' replacements for 74C193 and 74C161. | |

| − | + | Older TTL parts made by manufacturers such as [[Signetics]], [[Motorola]], [[Mullard]] and [[Siemens]] may have different numeric prefix and numbering series entirely, such as in the European FJ family FJH101 is an 8-input [[NAND gate]] like a 7430. | |
| + | |||
| + | A few alphabetic characters to designate a specific [[7400-series integrated circuits#Families|logic subfamily]] may immediately follow the '''74''' or '''54''' in the part number, e.g., 74LS74 for low-power [[Schottky diode|Schottky]]. Some CMOS parts such as 74HCT74 for high-speed [[CMOS]] with TTL-compatible input thresholds are functionally similar to the TTL part. Not all functions are available in all families. | ||
| + | The generic descriptive feature of these alphabetic characters was diluted by various companies participating in the market at its peak and are not always consistent especially with more recent offerings. The National Semiconductor trademarks of the words FAST<ref>{{cite web |title=FAST Advanced Schottky TTL Logic (1988, cover page) |url=https://archive.org/details/bitsavers_nationaldaFASTDatabook_31226275 |publisher= [[National Semiconductor]] |access-date=January 14, 2020}}</ref> and FACT | ||

| + | In a few instances, such as the 7478 and 74107, the same suffix in different families do not have completely equivalent logic functions. | ||
| + | |||
| + | Another extension to the series is the '''7416xxx''' variant, representing mostly the 16-bit-wide counterpart of otherwise 8-bit-wide "base" chips with the same three ending digits. Thus e.g. a "7416373" would be the 16-bit-wide equivalent of a "74373". Some 7416xxx parts, however, do not have a direct counterpart from the standard 74xxx range but deliver new functionality instead, which needs making use of the 7416xxx series' higher pin count. For more details, refer primarily to the Texas Instruments documentation mentioned in the [[#References|References]] section. | ||
| + | |||
| + | For CMOS (AC, HC, etc.) subfamilies, read "open drain" for "[[open collector]]" in the table below. | ||
| + | |||
| + | There are a few numeric suffixes that have multiple conflicting assignments, such as the 74453. | ||

| + | Parts in this section have a pin count of 14 pins or more. The lower part numbers were established in the 1960s and 1970s, then higher part numbers were added incrementally over decades. IC manufacturers continue to make a core subset of this group, but many of these part numbers are considered obsolete and no longer manufactured. Older discontinued parts may be available from a limited number of sellers as [[new old stock]] (NOS), though some are much harder to find. | ||

| + | For the following table: | ||
| + | * Part number column{{snd}} the "x" is a place holder for the [[7400-series integrated circuits#Families|logic subfamily]] name. For example, 74x00 in "LS" logic family would be "74LS00". | ||
| + | * Description column{{snd}} the terms Schmitt trigger, open-collector/open-drain, three-state were moved to the input and output columns to make it easier to sort by those features. | ||
| + | * Input column{{snd}} a blank cell means a normal input for the logic family type. | ||
| + | * Output column{{snd}} a blank cell means a "totem pole" output, also known as a [[push–pull output]], with the ability to drive ten standard inputs of the same logic subfamily ([[fan-out]] N<sub>O</sub> = 10). Outputs with higher output currents are often called drivers or buffers. | ||
| + | * Pins column{{snd}} number of pins for the [[dual in-line package]] (DIP) version; a number in [[parentheses]] (round brackets) indicates that there is no known dual in-line package version of this IC. | ||
