:= Chapter 5, Problem 24 P Bookmark Show all steps: Problem Use the Texas Instrument website to look up the 74ALS112A DFF (a) How long does it typically take to asynchronously clear a 74ALS112? (b) How long maximum does it take to asynchronously set a 74ALS112? (c) What is the shortest acceptable interval between active clock transitions for a 74ALS74A? (d) The J input of a 74ALS112A goes HIGH 15 ns before the active clock edge. The K input has been at o. Will the flip-fop be reliably set? (e) How long does it take (after the clock edge) to synchronously store a 1 in a cleared 74ALST4A D flip-flop?

Explanation / Answer

From the datasheet, 74ALS112A is JK flip flop and 74ALS74A is D flip flop

(a) 10ns.

(b) 20ns.

(c) 14.5ns.

(d) NO. setup time for data before clock signal (as per datasheet) is 22ns, so J input should be stable for atleast 22ns.

(e) 25ns.
