http://asic.co.in/Index_files/Timing_interview_questions.htm WebPositive D latch using transmission Gate: It consists of two transmission gates and two inverters. When Clk = high (1) T1 is ON and T2 is OFF, so output (Q) directly follows the input (D). When Clk = low (0) T1 is OFF and T2 is ON, now new data entering into the latch is stopped and we get only previously-stored data at the output.
