Abstract
A dual bus driver including a voltage input, a current source, a single data input, a first driver transistor for driving one bus, a second driver transistor for driving the other bus, a first pair of differential transistors for turning on either the first driver transistor or the second driver transistor to couple an input signal at the data input to the one bus or the other bus, and a second pair of differential transistors for disabling both driver transistors. By providing a driver that drives both buses, reduced power consumption, fewer circuit components and less integrated circuit layout complexities are achieved.
