What does TTL stand for in electronics?
Transistor-transistor logic
Transistor-transistor logic (TTL) is a digital logic design in which bipolar transistor s act on direct-current pulses. Many TTL logic gate s are typically fabricated onto a single integrated circuit (IC).
What is the use of TTL output?
TTL is an acronym for Transistor-Transistor Logic. It relies on circuits built from bipolar transistors to achieve switching and maintain logic states.
How does TTL work in networking?
Every time a router receives a packet, it subtracts one from the TTL count and then passes it onto the next location in the network. If at any point the TTL count is equal to zero after the subtraction, the router will discard the packet and send an ICMP message back to the originating host.
Why do we use TTL?
TTL is particularly well suited to bipolar integrated circuits because additional inputs to a gate merely required additional emitters on a shared base region of the input transistor. If individually packaged transistors were used, the cost of all the transistors would discourage one from using such an input structure.
How does TTL logic work?
Transistor-transistor logic (TTL) is a class of integrated circuits which maintain logic states and achieve switching with the help of bipolar transistors. One of the prominent features of transistor-transistor logic signals is the ability of the inputs of the gate rise to the logical “1” if left unconnected.
Is TTL cheaper than CMOS?
CMOS components are generally more expensive when compared to the TTL components. But on system-level, CMOS chips are less expensive as these are smaller in size as compared to the TTL chips.
What do you mean by fan out of a logic gate?
Fan-out is a term that defines the maximum number of digital inputs that the output of a single logic gate can feed. Most transistor-transistor logic ( TTL ) gates can feed up to 10 other digital gates or devices. Thus, a typical TTL gate has a fan-out of 10.
