Over 40 different logic subfamilies use this standardized part number scheme. Retrieved 30 May As integrated circuits in the series were made in different technologies, usually compatibility was retained with the original TTL logic levels and power supply voltages.

The 74H family is the same basic design as the family with resistor values reduced.

7400-series integrated circuits

Although the series was the first de facto industry standard TTL logic family i. Both transistors will be ON and voltage across both of them will be zero. Today, surface-mounted CMOS versions of the series are used in various applications in electronics and for glue logic in computers and industrial electronics.

Retrieved 26 March The 74H family provided a number of unique devices for CPU designs in the datasjeet. Here are a few examples where it is used. It was jokingly referred to in the Eastern Bloc dwtasheet industry as the “elephant-dung packaging”, due to its appearance. The Soviet integrated circuit designation is different from the Western series:.

The series of transistor—transistor logic TTL integrated circuits are the most popular family of TTL integrated circuit logic. A short-lived 64 prefix on Texas Instruments parts indicated an industrial temperature range; 74,s00 prefix had been dropped from the TI literature by 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.


The series contains hundreds of devices that provide everything from basic daasheet gatesflip-flopsand counters, to special purpose bus transceivers and arithmetic logic units ALU. The and series were used in many popular minicomputers in the s and early s.

Through the late s and s newer versions of this family were introduced to support the lower operating voltages used in newer CPU devices. With that both inputs of the gate will be LOW. Principles, Devices and Applications.

Submitted by admin on 3 April Originally the bipolar circuits provided higher speed but consumed more power than the competing series of CMOS devices. Around the production of standard logic ceased in all Eastern European countries except the Soviet Union and later Russia and Belarus.

When you want logic inverter. 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.

Many datasehet families maintain a consistent use of the device numbers as an aid to designers.

The 74LS family of ICs is a lower-power version of the 74S fatasheet, with slightly higher speed but lower power dissipation than the original 74 family; it became the most popular variant once it was widely available. Clones of the series were also made dattasheet other Eastern Bloc countries: After verifying the cases, you can tell that we have satisfied the above truth table.


The 74F family was introduced by Fairchild Semiconductor and adopted by other manufacturers; it is faster than the 74, 74LS and 74S families. Intypical quantity-one pricing for the SN military grade, in ceramic welded flat-pack was around 22 USD. 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 datashee the target device in IC form.

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.

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 ]. The chip datwsheet available in different packages and is chosen depending on requirement. We can use all four gates this way tosatisfy our needs. This chip has less transition times which are needed for high speed applications.
