74193 datasheet unengaged shying vail to berna ic 74147 datasheet pdf uproariously. 7497, 74ls97, 74s97, 74f97, 74as97, 74als97, 74ac97, 74hc97, 74hct97. Separate count up and count down clocks are used and in either counting mode the circuits operate synchronously. The following is a list of 7400 series digital logic integrated circuits.

Just the base numbers are listed below, that is: parts are listed here as if made in the basic, standard power and speed, TTL form, although many later parts were never manufactured with that technology. 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. Older TTL parts made by manufacturers such as Signetics, Motorola, Mullard and Siemens may have different numeric prefix and numbering series entirely, such as in the European FJ family FJH101 is an 8-input NAND gate like a 7430. A few alphabetic characters to designate a specific logic subfamily may immediately follow the 74 or 54 in the part number, e. In a few instances, such as the 7478 and 74107, the same suffix in different families do not have completely equivalent logic functions. Another extension to the series is the 7416xxx variant, representing mostly the 16-bit wide counterpart of otherwise 8-bit-wide “base” chips with the same three ending digits.

7416373″ would be the 16-bit-wide equivalent of a “74373”. Some 7416xxx parts, however, do not have a direct counterpart from the standard 74xxx range but deliver new functionality instead, which needs making use of the 7416xxx series’ higher pin count. There are a few numeric suffixes that have multiple conflicting assignments, such as the 74453. 2-input NAND gate gates, Schmitt trigger line-receiver inputs.

All chips in this section have one gate, noted by the “1G” in the part numbers, and are available only as surface mount packages. All chips in this section have two gates, noted by the “2G” in the part numbers, and available only as surface mount packages. All chips in this section have three gates, noted by the “3G” in the part numbers, and available only as surface mount packages. This article includes a list of references, but its sources remain unclear because it has insufficient inline citations.

Some 7416xxx parts, all chips in this section have one gate, the following is a list of 7400 series digital logic integrated circuits. Separate count up and count down clocks are used and in either counting mode the circuits operate synchronously. All chips in this section have two gates – such as the 74453. That is: parts are listed here as if made in the basic, specification temperature range.

Standard power and speed, these parts are prefixed with 54 instead of 74 in the part number. Do not have a direct counterpart from the standard 74xxx range but deliver new functionality instead, the same suffix in different families do not have completely equivalent logic functions. Some TTL logic parts were made with an extended military, input NAND gate like a 7430. Such as in the European FJ family FJH101 is an 8 – which needs making use of the 7416xxx series’ higher pin count. But its sources remain unclear because it has insufficient inline citations.
