Abstract
The present invention relates to a latch including two first N-channel transistors connected to a low supply potential and controlled by a clock signal; two second transistors respectively connecting the two first transistors to an inverted output terminal and to a non-inverted output terminal and respectively controlled by a data line and a complementary data line; two third P-channel transistors respectively coupling the two second transistors to a high supply potential and cross-controlled by the output terminals; and circuitry for maintaining the states of the output terminals when the first transistors are non-conductive.
