ABSTRACT:
A latch has a first mode in which the latch functions as a dynamic latch and a second mode in which the latch functions as a static latch. The latch has a feedback circuit that in turn has two parallel switchable loads. The first load is responsive to a data input signal of the latch in the first mode and disabled in the second mode. The second load is responsive to a clock signal in the second mode and disabled in the first mode. The switchable loads being in parallel provides for the ability to select the feedback that is better for the particular mode of operation. The first and second switchable loads can be optimized for the particular mode of operation that will use it.
