Absolute Maximum Ratings*
Temperature Under Bias .................................. -40°C to +85°C
Storage Temperature ..................................... -65°C to +150°C
Voltage on Any Pin with
Respect to Ground .........................................-2.0V to +7.0V(1)
Voltage on Input Pins
with Respect to Ground
During Programming.....................................-2.0V to +14.0V(1)
Programming Voltage with
Respect to Ground .......................................-2.0V to +14.0V(1)
*NOTICE:
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.
Note:
1. Minimum voltage is -0.6V DC, which may under-
shoot to -2.0V for pulses of less than 20 ns. Max-
imum output pin voltage is VCC + 0.75V DC,
which may overshoot to 7.0V for pulses of less
than 20 ns.
