With features such as this the 74C logic family is. 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. Specific functions are described in a list of series integrated circuits. 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 series contains hundreds of devices that provide everything from basic logic gatesflip-flopsand counters, to special purpose bus transceivers and arithmetic logic units ALU. They are useful for rapid breadboard -prototyping and for education and remain available from most manufacturers.

Nilar Retrieved 5 June All inputs datassheet protected from damage due to static dis. AC Parameters are guaranteed by DC correlated testing. But there are a few exceptions where incompatibilities mainly in pin-out across the subfamilies occurred, such as:. Maximum V CC Voltage. Today, surface-mounted CMOS versions of the series are used in various applications in electronics and for glue logic in computers and industrial electronics.

The 74S family, using Schottky circuitry, uses more power than the 74cc00, but is faster. Intypical quantity-one pricing for the SN military grade, in ceramic welded flat-pack was around 22 USD. The 74H family provided a number of unique devices for CPU designs in the s. The fastest types and very low voltage versions are typically surface-mount only, however. Capacitance is guaranteed by periodic testing. List of series integrated circuits. Datasyeet CC Supply Current.

Features s Wide supply voltage range: Part number schemes varied by manufacturer. Some TTL logic parts were made with an extended military-specification temperature range. Information Applikation Mikroelektronik in German.

Some examples of FJ series are:. Instead of the ubiquitous black resin, they had a brownish-green body colour with subtle swirl marks created during the moulding process. Retrieved 24 May Retrieved 30 May Function and pin out compatibility with series 74 devices minimizes design time for those designers already familiar with the standard 74 logic family.

The and series were used in many popular minicomputers in the s and early s. Clones of the series were also made in other Eastern Bloc countries: 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. Power Dissipation P D. 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 dtasheet.

The series of transistor—transistor logic TTL integrated circuits are the most popular family of TTL integrated circuit logic. Some companies have also offered industrial extended temperature range variants dafasheet the regular series part numbers with a prefix or suffix to indicate the temperature grade. TOP 10 Related.
