Abstract
An SR latch is provided, which comprises a D-type latch and a logic circuit connected between data and sense input of the D-type latch and set and reset input terminals of the SR latch circuit. The logic circuit establishes the logic levels of signals applied to the data and sense inputs of the D-type latch such that said SR latch circit can assume one of set, reset and hold states depending on the combination of the logic levels of the signals applied to the set and reset input terminals.
