A latch of an integrated circuit is able to retain data at the latch when the integrated circuit is in a low-power mode. The latch retains data at a retention stage in response to assertion of an isolation signal. In response to a reference voltage supplied to the latch being restored to a normal operating voltage, indicating that the integrated circuit has transitioned from the low-power mode to a normal mode, a data restoration circuit provides the retained data at the output of the latch prior to negation of the isolation signal. This reduces the likelihood that a delay in negation of the isolation signal will result in the latch output providing incorrect data, thereby reducing the likelihood of the latch output causing errors in downstream elements of the integrated circuit.
