Abstract
An integrated circuit (IC) comprising an integrated level shifting latch for I/O. The level shift in the IC I/O section may be clocked. In addition, a latch may be moved from the core section to the I/O section of the device, and thus the incoming clock may remain in the external voltage domain to clock the latch along with the level shift. The level shift and latch may be clocked on opposite phases of the clock. Preferably, the level shift and latch may operate differentially on the data signal. Both setup and clock-to-Q times are significantly reduced with respect to prior art devices, allowing higher speed industry specifications may be met.
