An integrated circuit (100) includes a current mode write driver (105). The write driver (105) includes a switching control circuit (110) including (i) a DC current control circuit (111) operable to directly convert a received ECL differential signal into first, second, third and fourth DC output currents (a, b, c, and d) and (ii) a boost current control circuit (112) operable to directly convert a received level shifted version of the ECL differential voltage signal and a delayed version of the ECL differential voltage signal into first, second, third and fourth boost output currents (a1, b1, c1, and d1). An H-bridge circuit (120) includes an output stage (125) including first and second current sourcing control nodes (126, 127) and first and second current sinking control nodes (128, 129). A first output node (131) is between the first sourcing and first sinking nodes (126, 128) and second output node between the second sourcing and the second sinking nodes (127, 129). A first, second, third and fourth current mirror including input is coupled to sourcing or sinking control nodes (126, 127, 128, and 129) and are each operable to receive one of the DC output currents and one of the boost output currents for switchably delivering current diagonally through a load (145) connected between the output nodes (131, 132).
