The IC Digital Logic Families

The IC Digital Logic Families:

· RTL-Resistor-Transistor Logic.

· DTL-Diode-Transistor Logic.

· I2L-Integrated-Injection Logic.

· TTL-Transistor-Transistor Logic.

· ECL-Emitter-Coupled Logic.

· MOS-Metal-Oxide Semi-conductor.

· CMOS-Complementary Metal-Oxide Semi-conductor.

Advantage of CMOS:

· Ckt is must simpler.

· Easy to fabricate.

· Faster.

· Power consumption is low.

· Comparatively cheeper.

Disadvantage of CMOS is the logic is always invert.
