Question

Schottky families prevent the saturating using ___________

(a) Transistors

(b) Schottky transistors

(c) Diodes

(d) Schottky diodes

This question was addressed to me during an interview for a job.

This intriguing question comes from Compatibility or Interfacing in portion Logic Families of Digital Circuits

Answer 1

Right choice is (d) Schottky diodes

To explain: Schottky families prevent the saturating using Schottky diodes across the base-collector junctions of transistors. In Saturation mode, the transistor is in “ON”mode, where it seems like a short circuit between collector and emitter.
