Types of Logic Families
Here is a list of various logic families introduced in rough chronological order of their introduction, along with their usual abbreviations:
Diode Logic (DL)
Direct-Coupled Transistor Logic (DCTL)
Complementary Transistor Logic (CTL)
Resistor-Transistor Logic (RTL)
Resistor-Capacitor Transistor Logic (RCTL)
Diode-Transistor Logic (DTL)
Emitter-Coupled Logic (ECL), also known as Current-Mode Logic (CML)
Transistor-Transistor Logic (TTL) and Variants
P-Type Metal Oxide Semiconductor Logic (PMOS)
N-Type Metal Oxide Semiconductor Logic (NMOS)
Complementary Metal-Oxide Semiconductor Logic (CMOS)
Bipolar Complementary Metal-Oxide Semiconductor Logic (BiCMOS)
Integrated Injection Logic (I2L)
These logic families represent different technologies and design approaches used in digital electronics over the years, each with its own advantages and limitations.
