Abstract
An output buffer, a slew-rate control circuit, a break-before-make circuit, and a current limited input amplifier are connected as a digital output driver. This provides a simple apparatus and method of switching current control and slew-rate control that limits power consumption of the digital output driver. To further minimize switching current, capacitors may be added to the break-before-make circuit. A comparator input circuit may be connected to the current limited input amplifier to form a comparator having a low-power-consuming digital output.
