Abstract
An integrated level shifting latch circuit receives an input signal in a first voltage domain and generates an output signal in a second voltage domain. Data retention circuitry operates in a transparent phase where a data value is subjected to a level shifting function and is written into the data retention circuitry dependent on the input signal. Control circuitry controls the data retention circuitry to operate in the transparent phase during a first phase of the clock signal and to operate in the latching phase during a second phase of the clock signal. Writing circuitry writes the data value into the data retention circuitry. Contention mitigation circuitry, during the transparent phase, reduces a voltage drop across at least one component within the data retention circuitry.
