For a given power supply voltage then, a differential system produces signals of twice the amplitude and therefore has twice as good noise immunity (6 dB higher signal-to-noise ratio) as a single-ended system. The main advantage of single-ended over differential signaling is that fewer wires are needed to transmit multiple signals. If there are ...
Normal TTL signals are single-ended, which means that each signal consists of a voltage on one wire, referenced to a system ground. [3] The "low" voltage level is zero to 0.8 volts, and the "high" voltage level is 2 volts to 5 volts. A differential TTL signal consists of two such wires, also referenced to a system ground.
Contrary to popular belief, differential signalling does not affect noise cancellation. Balanced lines with differential receivers will reject noise regardless of whether the signal is differential or single-ended, [1] [2] but since balanced line noise rejection requires a differential receiver anyway, differential signalling is often used on balanced lines.
The word "uno" means "one" in Italian and was chosen to mark a major redesign of the Arduino hardware and software. [7] The Uno board was the successor of the Duemilanove release and was the 9th version in a series of USB-based Arduino boards. [8] Version 1.0 of the Arduino IDE for the Arduino Uno board has now evolved to newer releases. [4]
Current mode logic (CML), or source-coupled logic (SCL), is a digital design style used both for logic gates and for board-level digital signaling of digital data.. The basic principle of CML is that current from a constant current generator is steered between two alternate paths depending on whether a logic zero or logic one is being represented.
Arduino Mega compatible board with 16 extra I/O pins and the same a board size as the Arduino Uno. As with the Arduino Mega, most shields that were designed for the Duemilanove, Diecimila, or Uno will fit, but a few shields will not fit because of interference with the extra pins.

In parallel transmissions multiple data differential pairs carry several signals at once including a clock signal to synchronize the data. In serial communications, multiple single-ended signals are serialized into a single differential pair with a data rate equal to that of all the combined single-ended channels.
A Single Ended Push–Pull (SEPP, SRPP or mu-follower [10]) output stage, originally called the Series-Balanced amplifier (US patent 2,310,342, Feb 1943). is similar to a totem-pole arrangement for transistors in that two devices are in series between the power supply rails, but the input drive goes only to one of the devices, the bottom one of ...
