8. Limiting values
[1] The following applies to the limiting values:
a) This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive
static charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated
maximum.
b) Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to V
SSIO
/V
SSCORE
unless otherwise noted.
[2] Including voltage on outputs in 3-state mode.
[3] Not to exceed 4.6 V.
[4] The peak current is limited to 25 times the corresponding maximum current.
[5] The maximum non-operating storage temperature is different than the temperature for required shelf life which should be determined
based on required shelf lifetime. Please refer to the JEDEC spec (J-STD-033B.1) for further details.
[6] Human body model: equivalent to discharging a 100 pF capacitor through a 1.5 k series resistor.
Table 6. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134).
