Abstract
A level shifter circuit is configured to receive first and second complementary input signals. Each of the first and second complementary input signals have a value of either a first supply voltage or a first reference voltage. The level shifter further includes a strong latch circuit operable in response to the first and second complementary input signals to drive one of first and second output signals to a second supply voltage and includes a weak latch circuit operable to drive the other of the first and second output signals to a second reference voltage.
