11Logic gate — A logic gate is an idealized or physical device implementing a Boolean function, that is, it performs a logical operation on one or more logic inputs and produces a single logic output. Depending on the context, the term may refer to an ideal… …
12Magnetic amplifier — The magnetic amplifier (colloquially known as a mag amp ) is an electromagnetic device for amplifying electrical signals. The magnetic amplifier was invented early in the 20th century, and was used as an alternative to vacuum tube amplifiers… …

14Open collector — A simple schematic of an open collector of an integrated circuit (IC). An open collector is a common type of output found on many integrated circuits (IC). Instead of outputting a signal of a specific voltage or current, the output signal is… …
15Open drain — is one of the many different electrical input/output standards in digital designs today. Definition The word drain in the term Open drain refers to the drain terminal of a MOSFET transistor. (The analogous term for BJT devices is open collector.) …
16Charlieplexing — is a technique proposed in early 1995 by Charlie Allen at Maxim Integrated Products for driving a multiplexed display in which relatively few I/O pins on a microcontroller are used to drive an array of LEDs. The method utilizes the tri state… …
17Chip select — An example SPI with a master and three slave select lines. Note that all four chips share the SCLK, MISO, and MOSI lines but each slave has its own slave select. Chip select (CS) or slave select (SS) is the name of a control line in digital… …
18Parallax Propeller — chip The Parallax P8X32A Propeller chip, introduced in 2006, is a multi core architecture parallel microcontroller with eight 32 bit RISC CPU cores.[1] …
19Design For Test — (aka Design for Testability or DFT ) is a name for design techniques that add certain testability features to a microelectronic hardware product design. The premise of the added features is that they make it easier to develop and apply… …
