The series of transistor—transistor logic TTL integrated circuits are the most popular family of TTL integrated circuit logic.

74LS00 Datasheet(PDF) – Fairchild Semiconductor

Several generations of pin-compatible descendants of the original family have since become de facto standard electronic components. The series contains hundreds of devices that provide everything from basic logic gatesflip-flopsand counters, to special purpose bus transceivers and arithmetic logic units ALU.

Specific functions are described in a list of series integrated circuits. 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 Since the s, new product families have been released to replace the original series.

Today, surface-mounted CMOS versions of the series are used in various applications in electronics and for glue logic in computers and industrial electronics. They are useful for rapid breadboard -prototyping and for education and remain available from most manufacturers. The fastest types and very low voltage versions are typically surface-mount only, however. Additional characters in a part number identify the package and other variations. While designed as a family of digital logic, some TTL chips were used in analogue circuits, such as Schmitt triggers [ citation needed ].

Like the seriesthe newer CMOS versions of the series are also usable as analogue amplifiers using negative feedback similar to operational amplifiers with only an inverting input [ citation needed ]. However, this type of circuit suffers from significant harmonic distortion and shortened component life.

Although the series was the first de facto industry standard TTL logic family i. The quad NAND gate was the first product in the series, introduced by Texas Instruments in a military grade metal flat package W in October The extremely popular commercial grade plastic DIP N followed in the third quarter of The and series were used in many popular minicomputers in the s and early s.

Hobbyists and students equipped with wire wrap tools, a ‘ breadboard ‘ and a 5-volt power supply could also experiment with digital logic referring to how-to articles in Byte magazine and Popular Electronics which featured circuit examples in nearly every issue. In the early days of large-scale IC development, a prototype of a new large-scale integrated circuit might have been developed using TTL chips on several circuit boards, before committing to manufacture of the target device in IC form.


This allowed simulation of the finished product and testing of the logic before the availability of software simulations of integrated circuits. Intypical quantity-one pricing for the SN military grade, in ceramic welded flat-pack was around 22 USD. Originally the bipolar circuits provided higher speed but consumed more power than the competing series of CMOS devices. Milspec -rated devices for use in extended temperature conditions are available as the series.

Texas Instruments also manufactured radiation-hardened devices with the prefix RSNand the company offered beam-lead bare dies for integration into hybrid circuits with a BL prefix designation. While companies such as Mullard listed series compatible parts in data sheets, [18] by there was no mention of the family in the Texas Instruments TTL Data Book.

Some companies have also offered industrial extended temperature range variants using the regular series part numbers with a prefix or suffix to indicate the temperature grade. As integrated circuits in xatasheet series were made in different dayasheet, usually compatibility was retained with the original TTL logic levels and power supply voltages.

Introducing Integrated Circuits

Over 40 different logic subfamilies use this standardized part number scheme. The 74H family is the same basic design as the family with resistor values reduced. The 74H family provided a number of unique devices for CPU designs in the s. Many designers of military and aerospace equipment used this family over a long period and as they need exact replacements, this family is still produced by Lansdale Semiconductor.

The 74S family, using Schottky circuitry, uses more power than datasheey 74, but is faster. The 74LS family of ICs is a lower-power version of the 74S family, with slightly higher speed but lower power dissipation than the original 74 family; it became the most popular variant once it was widely available. The 74F family was introduced by Fairchild Semiconductor and adopted by other manufacturers; it is faster than the 74, 74LS and 74S families.

Through the late s and s newer versions of this family were introduced to support the lower operating voltages used in newer CPU devices. Part number schemes varied by manufacturer. The part numbers for series logic devices often use the following designators:. For example, “SNN” signifies that the part is a series IC probably manufactured by Texas Instruments “SN” originally meaning “Semiconductor Network” [25] using commercial processing, is of the military temperature rating “54”and is of the TTL family absence of a family designatorits function being the quad 2-input NAND gate “00” implemented in a plastic through-hole DIP package “N”.

Many logic families maintain datasheef consistent use of the device numbers as an aid to designers. Often a part from a different 74×00 subfamily could be substituted ” drop-in replacement ” in a circuit, with the datashwet function and pin-out yet more appropriate characteristics for an application perhaps speed or power consumptionwhich was a large part of the appeal of the 74C00 series over the competing CDB series, for example.


But there are a few exceptions where incompatibilities mainly in pin-out across the subfamilies occurred, such as:.

Some manufacturers, such as Mullard and Siemens, had pin-compatible TTL parts, but with a completely different numbering scheme; however, data sheets identified the compatible number as an aid to recognition.

Some examples of FJ series are:. Instead of the ubiquitous 74le00 resin, they had a brownish-green body colour with subtle swirl marks created during the moulding process. It 7l4s00 jokingly referred to in the Eastern Bloc electronics industry as the “elephant-dung packaging”, due to its appearance. The Soviet integrated circuit designation is different from the Western series:. Before July the two letters from the functional description were inserted after the first digit of the series.

Clones of the series were also made in other Eastern Bloc countries: A number of different technologies were available from the Soviet Union, [28] [33] [34] [35] 74lz00 Czechoslovakia, [36] [31] Poland, [29] [31] and East Germany. Around the production of standard logic ceased in all Eastern European countries except the Soviet Union and later Russia and Belarus. From Wikipedia, the free encyclopedia.
