10. What is unique about TTL devices such as the 74SXX?
Options
A. These 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 gate transistors are silicon (S), and the gates therefore have lower values of leakage current.
C. The S denotes the fact that a single gate is present in the IC rather than the usual package of 2?6 gates.
D. The S denotes a slow version of the device, which is a consequence of its higher power rating.
Correct Answer: These 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.
