List of 7400 series integrated circuits

The following is a list of 7400 series digital logic integrated circuits. The SN7400 series originated with TTL integrated circuits made by Texas Instruments. Because of the popularity of these parts, they were second-sourced by other manufacturers who kept the 7400 sequence number as an aid to identification of compatible parts. As well, compatible TTL parts originated by other manufacturers were second sourced in the TI product line under a 74xx series part number.

Just the base numbers are listed below, that is: parts are listed here as if made in the basic, standard power and speed, TTL form, although many later parts were never manufactured with that technology.

Overview

Some TTL logic parts were made with an extended military-specification temperature range. These parts are prefixed with 54 instead of 74 in the part number. 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 equivalent CMOS circuits with a 74 prefix, for example the 74HC4066 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 - such as the CD40193 and CD40161 being pin-for-pin functional replacements for 74C193 and 74C161. There is some reference to double-borrowings, such as 74193 -> 40193 -> 74HC40193.^[1]

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 logic subfamily may immediately follow the 74 or 54 in the part number, e.g., 74LS74 for Low-power 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.

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 section.

For CMOS (HC, HCT, etc.) subfamilies, read "open drain" for "open collector" in the above table.

There are a few numeric suffixes that have multiple conflicting assignments, such as the 74453.

Older chips

Newer one gate chips

All chips in this section have one gate. The right digits of the part numbers are typically the same logic gate as older legacy chips.^[3][4][5]

In the part numbers below, the "x" after the "74" is a place holder for the logic family name, for example "74AUG1G" or "74LVC1G".

Newer two gate chips

All chips in this section have two gates. The right digits of the part numbers are typically the same logic gate as older legacy chips.^[3][4][5]

In the part numbers below, the "x" after the "74" is a place holder for the logic family name, for example "74AUG2G" or "74LVC2G".

Newer three gate chips

All chips in this section have three gates. The right digits of the part numbers are typically the same logic gate as older legacy chips.^[3][4][5]

In the part numbers below, the "x" after the "74" is a place holder for the logic family name, for example "74AUG3G" or "74LVC3G".
