B. 4
C. 5
D. 6
Answer:C
Motorola has offered MECL circuits in ______ logic families.
A. 3 B. 4 C. 5 D. 6
Explanation: Motorola has offered MECL circuits in five logic families: MECL I, MECL II, MECL III, MECL 10000 (MECL 10K) and MECL 10H000 (MECL 10KH). The full form of MECL is Motorola emitter coupled logic. ECL is a high speed BJT. It uses BJT differential amplifier with single input and restricted current to avoid the transistor going into saturation and thus turning off operation.
