Which of the following options is not true for a gated D-type flip-flop?
- A.
when clock is high, allows the input data (D) to pass through to the output (Q) (b) (c) u(d)
- B.
stores a single bit of data
- C.
uses a clock signal to control when the input data (D) is transferred to the output (Q)
- D.
when clock is low, allows the input data (D) to pass through to the output (Q)
Attempted by 95 students.
Show answer & explanation
Correct answer: D
A gated D-type flip-flop allows data to pass from input to output only when the clock signal is active, typically high. It stores the data state while the enable signal is asserted and holds it when inactive. Therefore, any statement suggesting that data passes through exclusively or primarily when the clock is low contradicts standard positive-level triggering logic.
