Patent ID: 8283964

Claim:
An apparatus comprising: a driver circuit including: a first and a second inverter and configured to receive a first and a second input signal of a differential input signal comprising Vinp and Vinn signals having a first voltage range at the first and second inverters, respectively, and provide a differential drive signal comprising Vdrp and Vdrn signals having a second voltage range different from the first voltage range; the first inverter to receive the Vinp signal and provide a first intermediate signal, a third inverter coupled to the first inverter and to receive the first intermediate signal and provide a first control signal, a first metal oxide semiconductor (MOS) transistor coupled to the third inverter and to receive the first control signal and provide the Vdrp signal, the second inverter to receive the Vinn signal and provide a second intermediate signal, a fourth inverter coupled to the second inverter and to receive the second intermediate signal and provide a second control signal, and a second MOS transistor coupled to the fourth inverter and to receive the second control signal and provide the Vdrn signal; and a latch coupled to the driver circuit and to receive the differential drive signal and provide an output signal having the second voltage range.
