Abstract:
An output buffer includes a pullup driver, a pulldown driver, and an output stage. The pullup driver has a drive control input, and an output for providing a pullup drive signal in a push-pull mode in response to receiving a first drive control signal on the drive control input, and in a current limited mode in response to receiving a second drive control signal on said drive control input. The pulldown driver has a drive control input, and an output for providing a pulldown drive signal in the push-pull mode in response to receiving a third drive control signal on the drive control input, and in the current limited mode in response to receiving a fourth drive control signal on the drive control input. The output stage provides a voltage on an output terminal in response to the pullup and pulldown drive signals.
