Which of the following logic families has the shortest propagation delay?
A. S-TTL
B. AS-TTL
C. HS-TTL
D. HCMOS
Answer:B
Which of the following logic families has the shortest propagation delay?
A. S-TTL B. AS-TTL C. HS-TTL D. HCMOS
Explanation: AS-TTL (Advanced Schottky) has a maximum clock frequency that is 105 MHz. So, the propagation delay will be given by 1/105 sec which is the lowest one. It is followed by S-TTL and HCMOS in terms of increasing propagation delay.
