Abstract
An integrated-circuit output driver generates, in response to an input signal constrained to a first voltage range, a control signal at one of two voltage levels according to a data bit conveyed in the input signal, the two voltages levels defining upper and lower levels of a second voltage range substantially larger than the first voltage range. The output driver generates an output-drive signal constrained to a third voltage range according to the one of the two voltage levels of the control signal, the third voltage range being substantially smaller than the second voltage range.
