Abstract
A small signal swing line driver, that generates a reduced amount of switching noise and also suppresses transients appearing on the line, is described. Specifically, the driver includes a clamp connected to the driver output to limit the maximum DC driver output level and to suppress voltage transients, e.g. reflections, spikes or the like, appearing on the driven line and caused by conditions external to the driver. The driver also contains circuitry to limit the transition times of the rising and falling edges of the driver output signal in order to reduce the amount of switching noise which is generated by the driver and thereafter coupled onto quiet lines.
