Ttl logic family has an output state known as?
true and false
What is ttl circuit?
A digital circuit composed of bipolar junction transistors (BJTs). Widely used in all variety of electronic applications, especially prior to CMOS circuits becoming popular, TTL superseded the earlier RTL (resistor-transistor) and DTL (diode-transistor) logic designs, which used more power. In TTL, transistors are used to both isolate inputs and perform the logic switching. A "TTL" designation on a circuit input or output indicates a digital circuit rather than analog.Read more: transistor-transistor-logic-electronics
Why do TTl integrated circuits assume unconnected inputs to be at logic?
Unused ttl inputs would normally default to logic 1 if left floating. but these inputs could act as antennas under certain conditions and they could pick up noise which can cause the circuit to malfunction.
Why ECL family is fastest?
ECL or emitter coupled logic is faster than TTL type logic because the switching transistors do NOT go into saturation in either the on or off state. The switching time from saturation in a high output to saturation in a low state like TTL requires that the junction capacitance be overcome and that the charge in the saturated junction get swept out. ECL is sensitive to a threshold level only.
What TTL Logic Voltage Level?
Historically, transistor-transistor logic (TTL) voltage levels have been 5.0 volts, with a high being any voltage above about 3.5 volts and a low being any voltage below about 1.5 volts, with lots of variations on the high/low cutoffs from part to part. Since about 2001, however, most processors have been using low-voltage TTL (LVTTL), which has a nominal voltage of 3.3 volts (approx >2.2 volts for high and approx < 1.2 volts for low). Hence, many parts advertised as "TTL" today actually work at 3.3 volts rather than 5.0 volts.
Whether TTL logic is preferred to DRL logic and why?
DRL cannot invert signals.
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 meant by ttl logic?
TTL stands for "transistor-transistor logic" and consists of using BJT's ("bipolar junction transistors") to conduct the logic for the circuit.
Which logic family is used to fabricate microprocessor?
TTL
What is TTl in digital electronics?
transistor transistor logic
Why is a TTL logic gate faster than a CMOS logic gate?
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.
What are the disadvantages of TTL logic family?
Briefly, TTL uses more power than more modern families.
What is full form of TTL used in PIC16f72 micro-controller?
In electronics TTL stands for Transistor Transistor Logic.
What is value of propagation delay of TTL logic?
it is in micro seconds
What are TTL gates?
TTL stand for transistor transistor logic it could be DTL for diode or any other type of family.
Why an open ttl gate behaves as a logic high input?
because TTL have a bias input setup to eliminate noise therefore the output will follow the logic one input if left open
