both are technologies in electronics,
dtl ->diode transistor logic
rtl ->resistor transistor logic
dtl in a bit newer than rtl
return to sedra book in electronics, chapter 14 in the 4th edition,
you can there find all u need about their application.
using any of these techniques u can make inverters, Nand gates and others
also u can easily make SR flip-flop using RTL
There is no difference.
There is no difference.
difference between aggressive mimicry and protective mimicry
what is the difference between a male coyoted and a female coyoted
There is no difference, they are same... Hole
because the amplifying function are performed by transistors (contrast with RTL and DTL).
1. advantages and disadvantages of RTL family?2. merits and demerits of DTL family ?
A: The characteristic will be the same as DTL RTL TTL the logic will not change but the transfer function for each family is certainly different
A: There are an awful lot of IC family that uses 5 volts buss. TTL RTL DTL including microprocessors
DTL Sourcing
Transistor-transistor logic (TTL) is a class of digital circuits built from bipolar junction transistors (BJT) and resistors. It is called transistor-transistor logic because both the logic gating function and the amplifying function are done by transistors.To know about the advantages of TTL logic family, one should have a basic idea about RTL, DTL etc. Diode logic (DL) uses diodes to implement logical functions like AND and OR. But the disadvantage is that it can not perform NOT operation. As AND and OR are not complete functions by themselves, they can not perform several logic functions without NOT. Hence, there was a need for some device which can perform a NOT function as diodes can not. That device is a transistor. Then came the DTL which uses a transistor along with diodes. As a transistor can act as an inverter, NAND (NOT-AND) & NOR (NOT-OR) operations can be performed. But this logic uses several diodes which will slow down its operation. Due to the delay offered by them, the logic levels may sometimes change i. e. 0 t0 1 or 1 to 0. Then came TTL. This logic uses a multi emitter transistor, a transistor with many emitter terminals. As every emitter is nothing but a diode, this logic eliminates the use of all diodes. This is the major advantage. As transistor becomes ON and OFF much rapidly than a diode, switching time will be faster.TTL, or Transistor-transistor logic replaced resistor-transistor logic, and used much less power. The TTL family is very fast and reliable, and newer faster, less power-consuming, etc. types are always being developed.ANSWER: ONE WORD SPEED
