A diode in general lets current flow more in one direction than the other. This can be used in many configurations in an electronic circuit, with one of the more common uses in memory and decision making circuits. With more of our electronic devices running on batteries, manufacturing processes are finally realizing that people will probably buy the device that has a longer battery life over other considerations. Wikipedia contributors contend that the metal-semiconductor junction switches faster and operates at lower voltage.

What are the available transistor-transistor logic subfamilies?
§ Low-power TTL (L), which traded switching speed (33ns) for a reduction in power consumption (1 mW) (now essentially replaced by CMOS logic)§ High-speed TTL (H), with faster switching than standard TTL (6ns) but significantly higher power dissipation (22 mW)§ Schottky TTL (S), introduced in 1969, which used Schottky diode clamps at gate inputs to prevent charge storage and improve switching time. These gates operated more quickly (3ns) but had higher power dissipation (19 mW)§ Low-power Schottky TTL (LS)- used the higher resistance values of low-power TTL and the Schottky diodes to provide a good combination of speed (9.5ns) and reduced power consumption (2 mW), and PDP of about 20 pJ. Probably the most common type of TTL, these were used as glue logic in microcomputers, essentially replacing the former H, L, and S sub-families.§ Fast (F) and Advanced-Schottky (AS) variants of LS from Fairchild and TI, respectively, circa 1985, with "Miller-killer" circuits to speed up the low-to-high transition. These families achieved PDPs of 10 pJ and 4 pJ, respectively, the lowest of all the TTL families.§ Low-voltage TTL (LVTTL) for 3.3-volt power supplies and memory interfacing.
Difrance between ic and ttl?
ic refers to integrated circuits and ttl refers to transistor transistor logic. ttl is a family which provides the basic or former structure of logic gates for example different logic gates such as NAND,NOR etc can be made out with the help of transistors connected in a specific manner. integerated circuits are the combination of logic gates presented on a base with equal number of input pins . for example IC-7408 contains 14 pins
What is multi emitter transistor?
A bipolar junction transistor with 2 or more emitters. The most common use of these was in the input section of transistor transistor logic (TTL) gates. They offered significantly higher speed and used less area on the IC chip than the diodes used in the input section of the diode transistor logic (DTL) gates that came earlier. This made TTL ICs both faster and cheaper than the DTL ICs which soon became obsolete.
What is rt in electronics?
I believe that is resistor transistor technology TTL transistor transistor logic
What is a TTL-compatible output?
Compatibility in TTL means that the output of one TTL device can be used to drive the Input of the other TTL device , This because the low and high output window fit inside the low and high input window/profile TTL stand for Transistor Transistor Logic, so any voltage between 0 and 5 volt is compatible where any voltage between 3V and 5V is logic 1 and zero volt is logic 0
What are TTL gates?
TTL stand for transistor transistor logic it could be DTL for diode or any other type of family.
What does transistor to transistor logic mean and what are its uses?
A: TTL-DTL-RTL are family of gates called by the name. Example TTL means Tran. trans. logic. It refers to the inputs for these gates as the type. T= Transistor D=Diode R=Resistor While they do perform the same function their characteristics in performance varies greatly.
What are the advantage of schottky TTL?
High speed operation.

What does TTL applies mean?
TTL is a logic family. A logic family is the set of logic gates designed using a specific approach. Or simply speaking, logic family is the way of implementing logic. TTL stands for transistor - transistor - logic. It involves transistors (BJT) to implement logic. TTL applies means TTL logic family is used or can be applied in that specific application.
