Abstract
An interface circuit receives an input signal IN having a first voltage amplitude from a first circuit, and outputs an output signal OUT having a second voltage amplitude to a second circuit. A level shifter comprises a first CMOS inverter and a second CMOS inverter which are cross-coupled, and a current limiting circuit that limits a current that flows through the first CMOS inverter and the second CMOS inverter, and converts the input signal IN into an intermediate signal INT which is a differential signal. A latch circuit receives the intermediate signal INT from the level shifter, and switches its state according to the positive signal and the negative signal of the intermediate signal INT.
