ABSTRACT:
A digital storage element comprises a master transparent latch that receives functional data signals from data input ports and scan data signals from a scan input port, the data input ports coupled to a four-input, one-output multiplexer that receives the functional data signals and selectively outputs one of the functional data signals. The element comprises a slave transparent latch coupled to the master transparent latch and comprising dedicated functional and scan data output ports. While operating in a scan mode, a first clock signal is used by the slave transparent latch and a second clock signal is used by the master transparent latch, wherein the first and second clock signals are non-overlapping. A first transistor is coupled to the master transparent latch and a second transistor is coupled to the slave transparent latch. When activated, the first or second transistor resets the element.
