Abstract
A line driver circuit can include an integrated circuit substrate of a first conductivity type having at least a first and a second well of a second conductivity type formed therein. The second well can be coupled to a first power supply node. A first transistor can be formed in the first well having a source coupled to a first input signal node, a drain coupled to a conductive line, and a gate coupled to a second input signal node. A second transistor can have a source coupled to a second power supply node, a drain coupled to the conductive line, and a gate coupled to the second input signal node. A third transistor can be formed in the second well and have a source coupled to the first power supply node, a drain coupled to the first well, and a gate coupled to receive a mode signal.
