The full form of MECL is ___________(a) Mono emitter coupled logic(b) Motorola emitter coupled logic(c) Motorola emitter capacitor logic(d) Both mono emitter and motorola coupled logicThe question was posed to me in unit test.Enquiry is from Compatibility or Interfacing in portion Logic Families of Digital Circuits

Answer»

Correct answer is (b) Motorola EMITTER coupled logic

To explain I would say: 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.
