What are the parameters of logic families?
What are the parameters of logic families?
Characteristics (Parameters) of Logic Families:
- Voltage and Current Parameters: Voltage Parameters (Threshold Levels):
- Fan-in and Fan-out: Fan-in :
- Noise Margin :
- Propagation Delay(Speed of operation) :
What are the three basic parameters for selecting digital logic family?
And that is the reason why we must be clear about different logic families and use the best combination of integrated circuits during the design of a digital system. The characteristics which are bound to be identical and used to compare performance are: Supply voltage range. Speed of response.
What are the parameters for evaluating and comparing logic families?
The most important parameters for evaluating and comparing logic families are: Power dissipation. Propagation delay. Noise margin.
What are the properties of digital logic families?
Classification and Characteristics of Digital Logic Family
- Propagation delay.
- Fan in and Fan out.
- Power dissipation.
- Noise Immunity and Noise margin.
- Figure of merit.
What are parameters of digital logic gates explain any two in detail?
Digital logic gates can have more than one input, for example, inputs A, B, C, D etc., but generally only have one digital output, (Q)….Digital Logic States.
| Boolean Algebra | Boolean Logic | Voltage State |
|---|---|---|
| Logic “1” | TRUE (T) | HIGH (H) |
| Logic “0” | FALSE (F) | LOW (L) |
What is TTL and ECL?
TTL (Transistor Transistor Logic) IC technology uses bipolar transistor as principal circuit element. CMOS (Complementary Metal Oxide Semiconductor) IC technology uses FET as principal circuit element. ECL (Emitter Coupled Logic) IC technology uses bipolar transistors configured as differential amplifier.
What is TTL family?
Transistor–transistor logic (TTL) is a logic family built from bipolar junction transistors. Its name signifies that transistors perform both the logic function (the first “transistor”) and the amplifying function (the second “transistor”), as opposed to resistor–transistor logic (RTL) or diode–transistor logic (DTL).
What is TTL in logic family?
What are the categories of logic families?
Four major logic families that predominated from the 1970’s through the 1990’s are Transistor-Transistor Logic (TTL), Complementary Metal-Oxide-Semiconductor Logic (CMOS, pronounced sea-moss), Low Voltage TTL Logic (LVTTL), and Low Voltage CMOS Logic (LVCMOS). Their logic levels are compared in Table 1.4.
What are digital logic families?
A logic family of monolithic digital integrated circuit devices is a group of electronic logic gates constructed using one of several different designs, usually with compatible logic levels and power supply characteristics within a family.
What are types of logic family?
The logic families which fall under the first kind are called bipolar families, this include diode logic (DL), emitted coupled logic (ECL), resistor transistor logic (RTL), diode transistor logic (DTL), transistor transistor logic (TTL).
