In the NAND gate, the transistors play the role of the switches. The emitter and the collector voltages vary in the opposite phase.
The TTL Nand gate is usually used in the design of various electric circuits.
The 74LS00 is a quad two input NAND gate with low power schottkey TTL implementation.

A: NAND implies not and to be true both input must be hi or true <> There are two flavors of NAND gate. The positive input/negative output NAND will have a low output if and only if both inputs are high. The negative input/positive output NAND will have a high output if and only if both inputs are low.
A: It is simply a function of negating a true input, the other characteristics s that it is limited in fan-in fan -out capabilities
The switching time (on and off) of the TTL logic gate is very fast in comparison with CMOS logic gate. However, they could not tolerate higher range of power supply.
The maximum input voltage for a NAND gate IC typically depends on its power supply voltage, which is usually specified in the datasheet of the specific IC. For common logic families like TTL, the maximum input voltage is generally around 2.0 to 5.5 volts, while CMOS NAND gates can handle a wider range, often up to the supply voltage (e.g., 3.3V or 5V). Exceeding the specified maximum input voltage can damage the IC. Always refer to the specific datasheet for exact limits.
The 7432 is a quad two input OR gate with TTL levels.
74LS08 is a quad two-input AND gate with LS-TTL logic levels.

because TTL have a bias input setup to eliminate noise therefore the output will follow the logic one input if left open
TTL (Transistor-Transistor Logic) inputs typically refer to the number of inputs that a TTL device, such as a logic gate or flip-flop, can handle. Common TTL logic gates often have 2 to 4 inputs, while more complex devices like multiplexers or encoders can have larger numbers of inputs, ranging from 4 to 16 or more. The specific number of TTL inputs depends on the type and design of the device in question.
