The logic families which fall under the first kind are called bipolar families, this include diode logic (DL), emitted coupled logic (ECL), resistor transistor logic (RTL), diode transistor logic (DTL), transistor transistor logic (TTL).
What are the characteristics of a CMOS logic family?
Characteristics of CMOS Logic Families CMOS supports a very large fan-out, more than 50 transistors. It has excellent noise immunity amongst all families. A logic low voltage for CMOS is about
How are the emitters of a logic family connected?
The emitters of the transistors are connected all together, hence the name ‘emitter-coupled’ logic families. The transistors in this system never saturate; their logic high and logic low levels are chosen close to one another, thus eliminating the possibility of saturation in the transistors.
