The NOT gate is a digital logic gate that behaves according to the truth table to the right. A HIGH output results if the inputs is LOW. If the input is HIGH, a LOW output results. NOT gates are also called inverters. A logic gate is an arrangement of controlled switches used to calculate operations using Boolean logic in digital circuits. ... Truth tables are a type of mathematical table used in logic to determine whether an expression is true or whether an argument is valid. ...





Symbols

There are two symbols for NOT gates: the 'military' symbol and the 'rectangular' symbol. For more information see Logic Gate Symbols A logic gate is an arrangement of controlled switches used to calculate operations using Boolean logic in digital circuits. ...

Hardware Description and Pinout

NOT Gates are basic logic gates, and as such they are recognised in TTL and CMOS ICs. The standard, 4000 series, CMOS IC is the 4049, which includes six independent NOT gates. The pinout diagram is as follows: TTL is an elite band of men and boys that originate, live or are involved in the tadley bmx scene. ...

Alternatives

If no specific NOT gates are available, one can be made from NAND gates in the configuration shown below. Any logic gate can be made from a combination of NAND gates NAND gates have the property, along with NOR gates, to be able to be combined to form any other kind of logic gate. ...

Encyclopedia4U - Menin Gate Memorial - Encyclopedia Article (412 words)
The Menin Gate Memorial at the eastern exit of the town of Ieper in Flanders, Belgium, marks the starting point for one of the main roads out of the town that led Allied soldiers to the front line during World War I.
Designed by Sir Reginald Blomfield and built by the British government, the Menin Gate Memorial opened on July 24, 1927 as a monument dedicated to the missing British and Commonwealth soldiers who were killed in the fierce battles around the Ypres Salient area who have no known grave.
The names of another 34,984 of those who died without graves in the area between August 16, 1917 and the end of the war, are recorded on plaques at the Tyne Cot Memorial to the Missing located just outside the village of Passchendaele which had been liberated by Canadian troops at great human cost.
