When the output of a standard TTL gate is HIGH, it can ________.
 
  A) sink 16mA of current from the attached input gates
  B) source 400-microamps of current to a maximum of 10 attached gates
  C) sink a maximum of 400-microamps from a maximum of 10 load gates
  D) source 16mA of current to a maximum of 10 attached gates

Question 2

What is unique about 74SXX-series TTL devices?
 
  A) The devices use Schottky transistors and diodes to prevent them from going into saturation; this results in faster turn on and turn off times, which translates into higher frequency operation.
  B) The S denotes a slow version of the device, which is a consequence of its higher power rating.
  C) The gate transistors are silicon (S), and the gates therefore have lower values of leakage current.
  D) The S denotes the fact that a single gate is present in the IC rather than the usual package of 2-6 gates.
