Abstract:
An I/O driver and related method are provided herein. The I/O driver includes circuitry for expediting the configuring of the corresponding output FET to operate in the linear region to reduce delay between the transition of the input signal and the corresponding transition of the output signal. Additionally, the I/O driver includes circuitry for controlling the slew rate at which the output signal transitions from a low logic state to a high logic state, or vice-versa. Further, the I.O driver includes circuitry for turning off the turned-on output FET before turning on the other output FET. This prevents “shoot-thru” current from flowing through the output FETs to reduce power consumption associated with the I/O driver.
