Abstract:
A method for converting data signals from one power supply voltage domain for use in another power supply voltage domain. The method includes receiving the data signal at a first node of the integrated circuit, wherein the first node is within the first power supply voltage domain. The method also includes generating a first intermediate differential signal from the data signal via a first conversion circuit of the integrated circuit. The method further includes communicating the first intermediate differential signal to a first cross-coupled latch, wherein the first cross-coupled latch generates a first output signal based on the first intermediate differential signal. The method also includes outputting the first output signal from a second node of the integrated circuit, wherein the second node is in the second power supply voltage domain. Other embodiments, such as an integrated circuit, and an input device, are also provided.
