Absolute Maximum Conditions[3]
Stresses greater than those listed in this table may cause
permanent damage to the device. These represent a stress
rating only. Operation of the device at these or any other condi-
tions above those specified in the operating sections of this
specification is not implied. Maximum conditions for extended
periods may affect reliability.

Notes:
3. Multiple Supplies: The voltage on any input or I/O pin cannot exceed the power pin during power-up. Power supply sequencing is NOT required.
4. All clock outputs loaded with 6" 60
Ω traces with 22-pF capacitors.
5. W144 logic inputs (except FS3) have internal pull-up devices (pull-ups not full CMOS level). Logic input FS3 has an internal pull-down device.
