摘要:
A logic device includes a data input, a scan test input, a clock demultiplexer, and a master latch. The clock demultiplexer is responsive to a clock input to selectively provide a first clock output and a second clock output. The master latch is coupled to the data input and to the scan test input and includes an output. The master latch is responsive to the first clock output of the clock demultiplexer and the second clock output of the clock demultiplexer to selectively couple the data input or the scan test input to the output.
