Abstract
A data output circuit for a semiconductor device with a level shifter and a method for outputting data using the same. The data output circuit comprises an output buffer for receiving and latching an input data signal with a first voltage range in response to a clock control signal to provide a pair of output data signals, a high-impedance controller/level shifter circuit for outputting high-impedance drive data for the control of a high-impedance state through a pair of output lines according to a first logic state of a high-impedance control signal and for receiving the output data signal pair from the output buffer according to a second logic state of the high-impedance control signal and transferring pull-up and pull-down output data signals with a second voltage range through the output lines, and an output driver for maintaining a data output terminal at the high impedance state in response to the high-impedance drive data from the high-impedance controller/level shifter circuit and for performing an output driving operation in response to the pull-up and pull-down output data signals from the high-impedance controller/level shifter circuit to output final data externally through the data output terminal. A data output speed and a high-impedance transition speed are improved and an excellent driving capability is obtained.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
