Abstract:
A master/slave latch includes an input stage, a master latch, a slave latch, and receives an asynchronous clear signal. The input stage is arranged to alternately pass or block a data input signal in response to a clock signal and a gated clock signal. The gated clock signal is the inverse of the clock signal when the asynchronous clear signal is not asserted, and the gated clock signal is not active when the asynchronous clear signal is asserted. The master latch receives and latches the passed data signal in a latched state, clears the latched state in response to the asynchronous clear signal being asserted, and generates a master latch output signal. The slave latch receives and latches the master latch output signal in a latched state. The cleared latched state is passed to the slave latch in response to the asynchronous clear signal being asserted.
