ABSTRACT:
A driver circuit limits the magnitude of the initial wave front launched onto a transmission line to a voltage that is approximately one-half of the supply voltage. Thus, immediately after the initial wave front is reflected from an open circuit receiver, a voltage at the receiver is approximately equal to the supply voltage when a rising voltage is launched, and ground when a falling voltage is launched.
