Which logic families are based on bipolar transistors?
The following sections are included:
- Diode logic.
- The bipolar junction transistor (BJT) and related logic families.
- The digital inverter and the resistor-transistor logic (RTL) family.
- The diode-transistor logic (DTL) family.
- The transistor-transistor logic (TTL) family.
- The emitter-coupled logic family (ECL)
What is transistor transistor logic family?
Transistor–transistor logic (TTL) is a logic family built from bipolar junction transistors. Its name signifies that transistors perform both the logic function (the first “transistor”) and the amplifying function (the second “transistor”), as opposed to resistor–transistor logic (RTL) or diode–transistor logic (DTL).
What are the different types of logic families?
• Logic families are sets of chips that may implement different logical functions, but use the same type of transistors and voltage levels for logical levels and for the power supplies. • These families vary by speed, power consumption, cost, voltage & current levels
What is the logic family of CMOS transistors?
Most logic today is based on CMOS logic families based on MOSFETs. Fig. 3.2 shows two types of CMOS transistors. CMOS transistors are MOSFETs; the C stands for complementary. The two types of transistors provide opposite polarities: when a gate voltage is applied, it enables current to flow between the source and drain.
When was the diode and transistor logic family invented?
A family of diode logic and diode–transistor logic integrated circuits was developed by Texas Instruments for the D-37C Minuteman II Guidance Computer in 1962, but these devices were not available to the public.
Which is the most common logic family in semiconductors?
The most common logic family in modern semiconductor devices is metal–oxide–semiconductor (MOS) logic, due to low power consumption, small transistor sizes, and high transistor density.
