Additional characters in a part number identify the package and other variations.

Although the series was the first de facto industry standard TTL logic family i. Retrieved 8 June So the total supply voltage appears across the transistors Q1 and Q2. Before July the two letters from the functional description were inserted after the first digit of the series. With these three cases we have realized the truth table for chip NAND gate.

7400-series integrated circuits

Retrieved 13 May While designed as a family of digital logic, some TTL chips were used in analogue circuits, such as Schmitt triggers [ citation needed ]. Retrieved 24 May The description for each pin is given below.


However, this type of circuit suffers from significant harmonic distortion and shortened component life. In the datasheeg days of uc 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. 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.

Submitted by admin on 3 April The 74F family was introduced by Fairchild Semiconductor and adopted by other manufacturers; it is faster than the 74, 74LS and 74S families.

Dataseet each gate has two inputs.

Motoroloa Semiconductor Products Inc. Retrieved from ” https: Integrated circuits Digital electronics introductions.

When both inputs are HIGH: This page was last edited on 22 Novemberat Retrieved 30 May With that the entire supply voltage appears across the transistor which is in OFF state.


Clones of the series were also made in other Eastern Bloc countries: 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. Originally the bipolar circuits provided higher speed but consumed more power than the competing series of CMOS devices.

The 74H family provided a number of unique devices for CPU designs in the s. Retrieved 26 March The series of transistor—transistor logic TTL integrated circuits are the most popular family of TTL integrated circuit logic. The 74H family is the same basic design as the family with resistor values reduced.

Even at this case output will be HIGH according to the truth table. Over 40 different logic subfamilies use this standardized part number scheme. Retrieved 7 March In the case when any one input is HIGH: From Wikipedia, the free encyclopedia. Retrieved 17 March
