ABSOLUTE MAXIMUM RATINGS*
Supply Voltage Range, VCC**...........................-0.6V to +7.0V
Supply Voltage Range, Vpp**.........................-0.6V to +14.0V
*Stresses greater than those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device. This is
a stress rating only and functional operation of the device at
these or any other conditions above those indicated in the
operation section of this specification is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
Input Voltage Range, All inputs except A9**....-0.6V to 6.5V
A9....-0.6V to +13.5V
Output Voltage Range**...............................-0.6V to VCC +1V
Operating Cage Temperature Range, TC.........-55°C to 125°C
Storage Temperature Range, Tstg.....................-65°C to 150°C
** All voltage values are with respect to GND.

NOTES:
1. VCC must be applied before or at the same time as G\ /VPP and removed after or at the same time as G\ /VPP. The deivce must not be inserted into or removed
from the board when G\ /VPP or VCC is applied.
2. G\ /VPP can be connected to VCC directly (except in the program mode). VCC supply current in this case is ICC + IPP
.
