Claim 13:
14. The transient-response level shifter of claim 13 wherein the first n-channel mirror transistor, the second n-channel mirror transistor, the first n-channel cross-coupled transistor, and the second n-channel cross-coupled transistor are each a standard n-channel transistor having a standard-n source-drain breakdown voltage;
wherein the first sensing transistor, the second sensing transistor, the first p-channel output transistor, the second p-channel output transistor, the first p-channel mirror transistor, and the second p-channel mirror transistor are each a p-channel transistor having a standard-p source-drain breakdown voltage;
wherein the first voltage-tolerant transistor and the second voltage-tolerant transistor are each an enhanced n-channel transistor fabricated to have an enhanced source-drain breakdown voltage that is greater than the standard-n source-drain breakdown voltage;
wherein an absolute value of the standard-p source-drain breakdown voltage is smaller than the enhanced source-drain breakdown voltage.
