The absolute maximum ratings are limiting values, to be applied individually, beyond which the device may be permanently damaged. Functional
operation under any of these conditions is not guaranteed. Exposing the device to its absolute maximum rating may
affect its reliability.

Note 1:
The presence of a Schottky diode for clamping bus overshoots will cause additional delays of signal edges. These delays are the result of diode
characteristics such as forward voltage, diode capacitance and the reverse recovery phenomenon. The ground clamp diode is most critical,
particularly if VLSI circuits such as static or dynamic memories are directly connected to busses without any buffer stages. The incremental delay
observed on a positive edge following a negative transition that forward biased the Schottky diode is less than 800 pS. That represents less than
10% of the 125 MHz (8 nS period) bus cycle time.
