Abstract

A level shifter circuit includes a high voltage latch circuit, a low voltage latch circuit, a high state pulse generator, and a low state pulse generator. The high voltage latch circuit includes a non-inverting output terminal, an inverting output terminal, a high state trigger input terminal, and a low state trigger input terminal. The low voltage latch circuit includes a high state trigger input terminal and a low state trigger input terminal. The high state trigger input terminal is coupled to the inverting output terminal of the high voltage latch circuit. The low state trigger input terminal is coupled to the non-inverting output terminal of the high voltage latch circuit. The high state pulse generator is coupled to the high state trigger input terminal of the high voltage latch circuit. The low state pulse generator is coupled to the low state trigger input terminal of the high voltage latch circuit.
