Note:
Stresses greater than those listed under 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 operational
sections of this specification is not implied.
Exposure to absolute maximum rating conditions
for extended periods may affect reliability.

Note:
[1]: VCC must be lowered to 0.2 V for at least 20 us in order to reset part.
[2]: Each I/O must be externally limited to a maximum of 25 mA and each octal (IO0_0 to IO0_7 and IO1_0 to IO1_7) must be limited to a maximum current of
100 mA for a device total of 200 mA.
[3]: The total current sourced by all I/Os must be limited to 160 mA.
