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.

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.

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.
