Which of the following logic families has the highest maximum clock frequency?
A. S-TTL
B. AS-TTL
C. HS-TTL
D. HCMOS
Answer:B
Which of the following logic families has the highest maximum clock frequency?
A. S-TTL B. AS-TTL C. HS-TTL D. HCMOS
Explanation: AS-TTL (Advanced Schottky) has a maximum clock frequency of 105 MHz. S-TTL (Schottky High Speed TTL) has 100 MHz. Found nothing as HS-TTL. There are H and S separate TTL. HCMOS has 50 MHz clock frequency.
