The White 68 lead G2/G2U CQFP
fills the same fit and function as
the JEDEC 68 lead CQFJ or 68
PLCC. But the G2/G2U has the
TCE and lead inspection advan-
tage of the CQFP form.

NOTES:
1. Stresses above the absolute maximum rating may cause permanent damage
to the device. Extended operation at the maximum levels may degrade
performance and affect reliability.
2. Minimum DC voltage on input or I/O pins is -0.5V. During voltage transitions,
inputs may overshoot V
SS
to -2.0 V for periods of up to 20ns. Maximum DC
voltage on output and I/O pins is V
CC
+ 0.5V. During voltage transitions,
outputs may overshoot to Vcc + 2.0 V for periods of up to 20ns.
3. Minimum DC input voltage on A
9
pin is -0.5V. During voltage transitions, A
9
may
overshoot Vss to -2V for periods of up to 20ns. Maximum DC input voltage on A
9
is +13.5V which may overshoot to 14.0 V for periods up to 20ns.
This parameter is guaranteed by design but not tested.
