Abstract
A circuit includes a first buffer configured to provide data on a signal line. The first buffer may be powered by a first power supply voltage. The circuit further includes a tri-state buffer coupled to receive the data provided on the signal line. The tri-state buffer may be powered by a second power supply voltage that has a magnitude greater than that of the first power supply voltage. During operation, the tri-state buffer may be activated for a predetermined period of time during which data is made available on the signal line.
