Abstract
An integrated circuit driver provides, among other things, a high data communication rate, a large common mode output voltage range, avoidance of spikethrough current that increases power consumption, improved switching speed using current-steering techniques, and improved matching of steady-state output current in the high logic state to that of the low logic state. The driver includes complementary differential pairs and associated current mirror circuits that differentially source/sink current at a pair of load conductors to drive the load conductors into a logic state. A single-ended embodiment is also described.
