Abstract
A method may be provided which controls the output impedance of a driver which includes within the driver an impedance circuit and a slew rate control. Accordingly, a desired output slew rate and a desired output impedance can be advantageously established and maintained over a wide range of variations in operating conditions, manufacturing processes and output voltage levels. Such a method also advantageously limits any crowbar current, thereby reducing the overall power consumption of the driver with little, if any, degradation of driver performance.
