Abstract
An apparatus includes a level shifter and a switching circuit. The level shifter includes an input, a first output, and second output having a logic value complementary to a logic value of the first output. The switching circuit includes a data input, a feedback input coupled to the second output of the level shifter, and an output coupled to the input of the level shifter. The switching circuit is configured to selectively latch, based on a select signal, a logic state of the level shifter at the second output.
