BIPOLAR LOGIC FAMILIES


Hi, this is my first post. This post is effective for the students who are studying Electronics and Communication Engineering (major in electronics) . From this topics you are able to know about the bipolar logic families. Other topics related with it will be discussed further.
BIPOLAR LOGIC FAMILIES:
The main elements of a bipolar are resistor , diode transistor ,capacitors
1.      SATURATED
1.      NON-SATURATED
The saturated bipolar logic ICs are:
1.      RTL-(RESISTOR- TRANSISTOR LOGIC)
2.      DCTL-(DIRECT- COUPLED TRANSISTOR LOGIC)
3.      I2L-(INTEGRATED-INJECTION LOGIC)
4.      DTL-(DIODE TRANSISTOR LOGIC)
5.      HTL-(HIGH-THRESHHOLD LOGIC)
6.      TTL-(TRANSISTOR-TRANSISTOR LOGIC)
The non-saturated bipolar logic ICs are:
1.      Schottky TTL,
2.      Emitter-coupled logic
UNIPOLAR LOGIC FAMILIES:
1.      PMOS-(P-CHANNEL)
2.      NMOS-(N-CHANNEL)
3.      CMOS(COMPLEMENTARY both p and n channel)
CHARACTERISTICS OF DIGITAL ICs:
1.      Speed of operation.
2.      Power dissipation.
3.      Figure of merit.
4.      Fan-out.
5.      Current and Voltage parameters.
6.      Noise immunity.
7.      Operating temperature range.
8.      Power supply requirements
9.      Flexibilities available.
THIS IS ALL FOR THIS TIME
