"TTL" stands for "Transistor to Transistor Logic". It's a very low current level communication protocol, typically used for very short distances. It also tends to be very sensitive to static and static discharge. It's the communication that is most commonly used between IC chips on a PC board.

Which logic family has the least propagation delay?

Here are the propagation delays for these gatesa) ECL = 2nsb) TTL = 1.5-33ns depending on the type of TTL. Conventional TTL is 9ns, Advanced Schottky TTL is 1.5nsc) RTL = 25nsd) CMOS = 5-20ns depending on if it is conventional CMOS, TTL pin compatible CMOS, high speed TPC CMOS or TTL compatible CMOSSo the fastest would be the Advanced Schottky TTL (74ASxx) at 1.5ns but the choice simply said TTL which I would interpret as Conventional TTL (74xx/54xx) which would have a propagation delay at 9ns.So the winner is ... (a) ECL which has a propagation delay at 2ns.

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.

What is the line of business of TTL?

TTL in the ISO/OSI Stack (IP Networks) ======================= TTL (Time To Live) is the time a message has to live given in hops. Each time the package is forwarded this counter counts down. With the TTL one avoids a datagram being routed in circles and cloaking the "intertube"'s up.

What is the purpose of the TTL field within a ip packet header?

The TTL field is between 0-255, and the TTL is decremented one value for each hop (each router the IP packet traverses). This means, that once an IP packet hits zero in the TTL, the router will drop the packet. For local traffic (traffic that is never meant to leave the local subnet), a TTL of 1 is used. If we didn't have TTL in our IP packets, they would just loop without end. Incidentally, this is the problem with Layer 2 bridging. Layer 2 traffic has no TTL, and that is why Layer 2 network can have those pesky bridging loops.

What is the difference ttl and cmos?

{| ! CMOS ! TTL | CMOS has good packing density. TTL takes up more space CMOS has better noise immmunity. TTL has a smaller noise immunity range CMOS has a large fan out. TTL can power less inputs CMOS consume less power. TTL use more power CMOS are highly static sensitive. TTL IC's tend to be less susceptible to static electricity CMOS uses FETS (Field-Effect Transistors) TTL uses BJTs (Bipolar junction Transistors CMOS can run with a range of supply voltages. TTL IC's run with a 5V supply. CMOS uses Vdd and Vss for it's power connections TTL uses BJTs (Bipolar junction Transistors CMOS takes a lot less power and is therefore suitable for battery applications, but generally speaking can't run as fast. TTL devices can drive more power into a load. CMOS chips can be damaged by static electricity: even a static jolt that you or I can't feel might destroy a CMOS chip! |}

What is a TTL-compatible output?

A: TTL gates operates on the premise of having +5 dc on the rail therefore the output will be in the range +5 volts. A cmos gate while similar to a TTL function is not really compatible since the output volts can be 12 volts or more. Besides that TTL gates require some input current for it to operate
