Almost all integrated circuits (ICs) have at least two pins which connect to the power rails of the circuit they are installed in. These are known as the IC's power supply pins. However, the labeling of the pins varies by IC family and manufacturer. ...more on Wikipedia about "IC power supply pin"
An integrated circuit (IC) or often referred to as a microchip or simply chip is a miniaturized electronic circuit (consisting mainly of semiconductor devices, as well as passive components) which has been manufactured on a thin substrate of semiconductor material. ...more on Wikipedia about "Integrated circuit" It's real http://www.shortopedia.com feeling!
Integrated circuit design, or IC design, is a subset of electrical engineering, encompassing the particular logic and circuit design techniques required to design integrated circuits, or ICs. ICs consist of miniaturized electronic components built into an electrical network on a monolithic semiconductor substrate by photolithography. Designing ICs is an difficult undertaking for several reasons: ...more on Wikipedia about "Integrated circuit design"
The Intel 8259 is a family of Programmable Interrupt Controllers (PICs) designed and developed for use with the Intel 8085 and Intel 8086 8-bit and 16-bit microprocessors. The family originally consisted of the 8259, 8259A, and 8259B PICs, though a number of manuafactures make a wide range of compatible chips today. The 8259 acts as a multiplexer, combining multiple interrupt input sources into a single interrupt output to interrupt a single device. ...more on Wikipedia about "Intel 8259"
In digital logic, an inverter is a logic gate which inverts the digital signal driven on its input. It is also called NOT gate. The truth table of the gate is as follows: ...more on Wikipedia about "Inverter (logic gate)"
A latchup is the inadvertent creation of a low-impedance path between the power supply rails as a result of triggering a parasitic device, which then opens and acts as a short circuit, leading to ceasement of proper function of the part and perhaps even its destruction with the overcurrent. A soft reset will not correct the situation; a power cycle is required. ...more on Wikipedia about "Latchup"
The 74 in the above list can be replaced with 54 to generate the 5400 series. The 5400 series were functionally the same as the 7400 series but with wider operating and storage temperature ranges, better resistance to vibration and mechanical shock, and other abuse. The more robust 5400 series was built to military specifications, commonly known as milspec. ...more on Wikipedia about "List of 7400 series integrated circuits"
A mask work is a two or three-dimensional layout of an integrated circuit (IC or "chip"), i.e. the arrangement on a chip of semiconductor devices such as transistors and passive electronic components such as resistors and interconnections. By extension, it also refers to the intellectual property right conferring time-limited exclusivity to reproduction of a particular layout. The layout is called a mask work because, in photolithographic processes, the multiple etched layers within actual ICs are each created using a mask, called the photomask, to permit or block the light at specific locations, sometimes for hundreds of chips on a wafer simultaneously. ...more on Wikipedia about "Mask work"
The MK484 AM Radio IC is a fully-functional AM radio detector on a chip. It is constructed in a TO-92 case, resembling a small signal transistor.
