ABSTRACT:
An off-chip driver circuit can operate in an output mode to drive a signal supplied at its input terminals to an output terminal. It can also operate in an input mode in which signals are driven from an external circuit via the output terminal onto the chip. In an output mode, the output terminal is clamped to reduce the effect of overshoot voltages, for example as a result of reflections from the external circuits.
