AC ELECTRICAL CHARACTERISTICS
(Commercial: VCC = 3.3V ± 0.3V, TA = 0°C to +70°C; Industrial: VCC = 3.3V
± 0.3V, TA = -40°C to +85°C)
NOTES:
1. Pulse widths less than minimum values are not allowed.
2. Industrial temperature range product for the 15ns speed grade is available as a standard device.
3. Values guaranteed by design, not currently tested.
4. tSKEW2 applies to synchronous
PAE and synchronous PAF only.
