Here what we do is, we use the simple inverter parts and make any gate using it as a primary module. inverter work as follows.
This is made out of two transistors NPN and PNP when we give high input(0.7)(which is connected to the base of NPN ad collector of PNP) it stops the current coming from the PNP form going towards the input and make it go towards base of NPN. This F/W bias the NPN and V(CE) become 0.2V and then as V(E) = 0, V(C) become 0.2V. Which is logic low.
When we supply logic low as the input current from PNP goes towards input and not to base of NPN this make NPN R/W bias and collector voltage have to choose the high value

What is the application of TTL in integrated circuits?
Transistor transistor logic is one type of many different types of bipolar transistor based digital logic circuitry. It is very efficiently implemented in integrated circuit chips, needs only one power supply voltage, and operates at reasonably high speeds. Transistor transistor logic was first developed in the middle 1960s as a modification of the diode transistor logic, then in use in some digital logic integrated circuit chips but dating back to the earliest discrete bipolar transistor logic developed in the late 1950s and derived from vacuum tube point contact diode logic used in many early first generation computers. Transistor transistor logic integrated circuits dominated the computer and electronic digital controller market from the late 1960s until the middle 1980s, when metal oxide semiconductor field effect transistor based microprocessors and microcontrollers began to replace it. By the early 1990s transistor transistor logic and other bipolar transistor based digital logic integrated circuits had been replaced with equivalent complementary metal oxide semiconductor field effect transistor integrated circuits that were both faster and consumed less power (thus running much cooler) or with programmable logic devices of various types. In general transistor transistor logic is now considered obsolete.

Why your 2001 Pontiac bonniville has no fuel injection?
It does have fuel injection. It may not be working but it has it. If it is not working then the fuel pump may have failed or the fuse is blown or relay is bad.

What is a logical device?
A logic device is a basic type of integrated circuit that is used to perform operations such as mathematical calculations.
What is advantage of CMOS setup?
CMOS is a type of technology for constructing integrated circuits. One advantage of this setup is less waste heat compared to NMOS logic or transistor-transistor logic.
Why the name is Transistor-transistor logic?
TTL - transistor-transistor logic uses connections between transistors to perform logic functions, rather than connections using resistors or diodes.T - transistor input stage (logic section)T - transistor output stage (power gain section)L - logicEarlier logic families like DTL (D - diode input stage) and RTL (R - resistor input stage) used different components in the input circuit and simpler output circuits.Later logic families like IIL (Integrated Injection Logic) and CMOS (Complimentary Metal Oxide Semiconductor) used entirely different circuits without separating into input (logic) and output (power gain) stages and significantly reduced power consumption, making dramatically higher levels of integration practical.
What is direct couple transistor logic?
Direct coupled transistor logic is a type of transistor that is more economical to use then integrated circuits. These transistors can be found in many types of wires such as the ones that control cable internet.
