Absolute Ratings and Operating Conditions
Absolute Ratings and Operating Conditions
Stresses greater than those listed may cause permanent damage to the device. This is a
stress rating only, and functional operation of the device at these or any other condi-
tions outside those indicated in the operational sections of this specification is not im-
plied. Exposure to absolute maximum rating conditions for extended periods may ad-
versely affect reliability.

1. During signal transitions, minimum voltage may undershoot to −2V for periods less than
20ns.
Notes:
2. During signal transitions, maximum voltage may overshoot to VCC + 2V for periods less
than 20ns.
3. VPPH must not remain at 12V for more than 80 hours cumulative.

1. Specifications apply to 60, 70, and 80ns devices unless otherwise noted. The 60ns device
is available upon customer request.
Notes:
2. For the 80ns device, I/O supply voltage (VCCQ ≤ VCC) = 1.65V (MIN) and 3.6V (MAX). For
the 60ns and 70ns devices, I/O supply voltage (VCCQ ≤ VCC) = 2.7V (MIN) and 3.6V (MAX).
