Abstract
The present disclosure describes exemplary line drivers for use in an exemplary wireline transmission device. In some situations, the exemplary line drivers are electrically connected to a wireline communication channel to transmit information. The exemplary line drivers prevent charge sharing with the wireline communication channel. The exemplary line drivers disclosed herein charge various circuit nodes to various logical values, such as a logical zero or a logical one, to prevent charge sharing with the wireline communication channel.
