DIGITAL LOGIC FAMILY The basic Classification of the Logic Families are as follows: A) Bipolar Families B) MOS Families C) Hybrid Devices A) Bipolar Families: 1. Diode Logic (DL) 2. Resistor Transistor Logic (RTL) 3. Diode Transistor Logic (DTL) 4. Transistor- Transistor Logic (TTL) 5. Emitter Coupled Logic (ECL) or Current Mode Logic (CML) 6. Integrated Injection Logic (IIL) B) MOS Families: 1. P-MOS Family 2. N-MOS Family 3. Complementary-MOS Family • Standard C-MOS • Clocked C-MOS • Bi-CMOS • Pseudo N-MOS • C-MOS Domino Logic • Pass Transistor Logic C) Hybrid Family: Bi-CMOS Family CMOS Family TTL Family WHAT IS LOGIC FAMILY Logic families are groups of logic circuits that are based on particular types of elements (resistors, transistors, and so forth). Families are identified by the manner in which the elements are connected, and, in some cases, by the types of elements used. CMOS v/s TTL There are two different types of computer chips: CMOS and TTL.
