There are several families of logic ICs numbered from 74xx00 onwards with letters xx in the middle of the number to indicate the type of circuitry, eg 74LS00 and 74HC The original family now obsolete had no letters, eg For each IC there is a diagram showing the pin arrangement and brief notes explain the function of the pins where necessary. For simplicity the family letters after the 74 are omitted in the diagrams below because the pin connections apply to all ICs with the same number. If you are using another reference please be aware that there is some variation in the terms used to describe pin functions, for example reset is also called clear.

Archived from the original on 28 February Retrieved October 14, The quad NAND gate was the first product in the series, 74xx series datasheet by Texas Instruments in a military grade metal flat package W in October These parts are prefixed with 54 instead of 74 in the part number. Intypical quantity-one pricing for the SN military grade, in ceramic welded flat-pack was around 22 USD. As board designs have migrated away from large amounts of logic chips, so has the need for many of the same gate in one package.
Part number schemes varied by manufacturer. List of books about 74xx series datasheet integrated circuits. A number of different technologies were available from the Soviet Union,      Czechoslovakia,   Poland,   and East Germany. PROMthree-state outputs. Retrieved 13 May Around the production of 74xx series datasheet logic ceased in all Eastern European countries except the Soviet Union and later Russia and Belarus.
Articles lacking in-text citations from June All articles lacking in-text citations. These parts are prefixed with 54 instead of 74 in the part number. Several generations of pin-compatible descendants of the original family have since become de facto standard electronic components.
Over 40 different logic subfamilies use this standardized part number scheme. While companies such as Mullard listed series compatible parts in data sheets,  by there was datasneet mention of the family in the Texas Instruments TTL Data Book. Retrieved 2 November 74xx series datasheet series of transistor—transistor logic TTL integrated circuits are the most popular family of 74xx series datasheet integrated circuit logic.
All articles with dead external links Articles with dead external links from July CS1 maint: While designed as a family of digital logic, some 74xx series datasheet chips were used in analogue circuits, such as Schmitt triggers [ citation needed ]. All chips in the following sections are available only in various 4, 5, 6, 8 pin surface mount 74xx series datasheet. Since the s, new product families have been released to replace the original series.
Some TTL logic parts were made with an extended military-specification temperature range. See List of series integrated circuits. Instead of the ubiquitous black 74xx series datasheet, they had a brownish-green body colour with subtle swirl marks created during the moulding process.
Originally the bipolar circuits provided higher speed but consumed more power than the competing series of CMOS devices. IC manufacturers continue to make a core subset of this group, but 74xx series datasheet of these part numbers are considered obsolete and no longer manufactured.
From Wikipedia, the free encyclopedia. Before July the two letters from the dtaasheet description were inserted after the first digit of the series. A short-lived 64 prefix on Texas Instruments parts indicated an industrial temperature range; this prefix had been dropped from the TI literature by Retrieved 8 June For more details, refer primarily to the Texas Instruments documentation mentioned in the References section.
A few alphabetic characters to designate a specific logic subfamily may immediately 74xx series datasheet the 74 74xx series datasheet 54 in the part number, e. The 74H 74xx series datasheet is the same basic design as the family with resistor values reduced.
They are useful for rapid breadboard -prototyping and for education and remain available from most manufacturers. Retrieved 17 March Not all functions are available in all families. Additional characters in a part number identify the package and other variations.

ABLab Solutions is one of the best, which provides really a very nice environment and faculty to educate students regarding Embedded Systems. Teaching is simple and efficient. Teacher and student introduction was good. Course is helpful for future.

The following is a list of series digital logic integrated circuits. The original series integrated circuits were made by Texas Instruments with the prefix "SN" to create the name SN74xx. Due to the popularity of these parts, other manufacturers released pin-to-pin compatible logic devices which kept the sequence number as an aid to identification of compatible parts. However, different manufacturers use different prefixes or no prefix at all.
