The 74181 implements all 16 possible logical functions with two variables. Its arithmetic functions include addition and subtraction with and without carry. It can be used with active-high data, in which a high logic level corresponds to 1, and active-low data, in which a low logic level corresponds to 1. [4]
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. [1]A short-lived 64 prefix on Texas Instruments parts indicated an industrial temperature range; this prefix had been dropped from the TI literature by 1973.
A United States data item description (DID) is a completed document defining the data deliverables required of a United States Department of Defense contractor. [1] A DID specifically defines the data content, format, and intended use of the data with a primary objective of achieving standardization objectives by the U.S. Department of Defense .
The first part number in the series, the 7400, is a 14-pin IC containing four two-input NAND gates. Each gate uses two input pins and one output pin, with the remaining two pins being power (+5 V) and ground. This part was made in various through-hole and surface-mount packages, including flat pack and plastic/ceramic dual in-line.
The Joint Electronics Type Designation System (JETDS), which was previously known as the Joint Army-Navy Nomenclature System (AN System. JAN) and the Joint Communications-Electronics Nomenclature System , is a method developed by the U.S. War Department during World War II for assigning an unclassified designator to electronic equipment.
LM393 differential comparator manufactured by National Semiconductor. The following is a list of LM-series integrated circuits.Many were among the first analog integrated circuits commercially produced since late 1965; [1] some were groundbreaking innovations [opinion].
The 704th Military Intelligence Brigade, a subordinate unit of the U.S. Army Intelligence and Security Command, conducts synchronized full-spectrum signals intelligence, computer network, and information assurance operations directly and through the National Security Agency to satisfy national, joint, combined and Army information requirements.
