WebAug 29, 2024 · Add a comment. 0. When set or reset is 'HIGH', irrespective of clock, output should be made 1 or 0. In the first case every event happens at the positive edge of clock. So even if set/reset was 'HIGH', it waits until the posedge clk to change the output. So it is not asynchronous. In second case whenever reset/set is 'HIGH' the always block is ... WebThe 74LVC74A is a dual edge triggered D-type flip-flop with individual data (nD) inputs, clock (nCP) inputs, set (n S D) and (n R D) inputs, and complementary nQ and n Q outputs. The set and reset are asynchronous active LOW inputs and operate independently of the clock input. Information on the data input is transferred to the nQ output on the ...

WebAug 13, 2024 · Even if you don't reset 2FF-synchroniser, you can still make it work. When such a 2FF-synchroniser is initially power-on and clocked, it drives an unknown value at its output for 2 clock cycles at most. In the next clock cycle, output will be driven to the actual value as at the valid input.
