The Voltages Applied to the Input of Any Standard TTL

Multiple Choice

The voltages applied to the input of any standard TTL series IC must never exceed +5.5 v because:

A) a greater voltage applied to a collector can cause a reverse breakdown of the B- C junction.
B) a greater voltage applied to a base input can cause reverse breakdown of the E- B junction Of Q₁.
C) a greater voltage applied to an emitter input can cause reverse breakdown of the E- B junction Of Q₁.
D) a greater voltage applied to a base can cause a reverse breakdown of the B- C junction.
