What is unique about TTL devices such as the 74SXX?

1.	What is unique about TTL devices such as the 74SXX?
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 2â€“6 gates.
D.	the s denotes a slow version of the device, which is a consequen ce of its higher power rating.
Answer» B. the gate transistors are silicon (s), and the gates therefore have lower values of leakage current.
