Absolute Maximum Ratings
WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current, temperature,
etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
Recommended Operating Conditions (See Warning Below)
Notes:
1. Maximum DC voltage on input and I/O pins is V
DD
+0.2V. During voltage transitions, inputs can positive overshoot to
V
DD
+1.0V for periods of up to 5 ns.
2. Minimum DC voltage on input or I/O pins is -0.3V. During voltage transitions, inputs can negative overshoot V
SS
to -1.0V for
periods of up to 5ns.
WARNING:
Recommended operating conditions are normal operating ranges for the semiconductor device. All the de-
vice’s electrical characteristics are warranted when operated within these ranges.
Always use semiconductor devices within the recommended operating conditions. Operation outside these ranges can
adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented on the data sheet.
Users considering application outside the listed conditions are advised to contact their FUJITSU representative before-
hand.
