9. Limiting values
[1] The following applies to Limiting values:
a) Stresses above those listed under Ta ble 12 may cause permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any conditions other than those described in Table 13 “DC electrical characteristics”, Table14“AC
characteristics” and Table 15 “AC characteristics (P89LPC901)” of this specification are not implied.
b) 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.
c) Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to V
SS
unless
otherwise noted.
Table 12: Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134).
