Absolute Maximum Ratings
Stresses greater than those listed in this table may cause per-
manent damage to the device. These represent a stress rating
only. Operation of the device at these or any other conditions
above those specified in the operating sections of this specifi-
cation is not implied. Maximum conditions for extended peri-
ods may affect reliability.

Notes:
1. All clock outputs loaded with 6" 60Ω transmission lines with 20-pF capacitors.
2. W48C101-01 logic inputs have internal pull-up devices, except SEL100/66# (pull-ups not full CMOS level).
