Abstract
Systems and methods for a low hold-time sequential input stage provide circuitry that includes a first latch element receiving a first input. The first latch element is connected to a first two-input multiplexer. The circuitry further includes a second latch element receiving a second input. The second latch element is connected to the first two-input multiplexer. The first input and the second input originate from different input cells of an input column that receive a same source signal.
