Abstract
An apparatus for providing active mode power reduction for circuits having data retention includes a master slave flip flop (MSFF) for latching a data input. An output level shifter (OLS), coupled to the MSFF, retains the data input in response to the MSFF being operable in an active power saving mode (APSM) to reduce power. The OLS operating in the APSM provides a level shifter output having a configurable voltage, thereby providing output isolation. A change in an operating mode of the MSFF between an active mode and the APSM is independent of a retention (RET) mode input.
