AC ELECTRICAL CHARACTERISTICS(1)
(Commercial: VCC = 5V ± 10%, TA = 0
°C to +70°C; Industrial: VCC = 5V ± 10%, TA = –40°C to +85°C; Military: VCC = 5V ± 10%, TA = –55°C to +125°C)
NOTES:
1. Timings referenced as in AC Test Conditions.
2. Industrial temperature range product for 15ns and 25ns speed grades are available as a standard device.
3. Industrial temperature range product for 25ns speed grade only is available as a standard device. All other speed grades are available by special order.
4. Pulse widths less than minimum are not allowed.
5. Values guaranteed by design, not currently tested.
6. Only applies to read data flow-through mode.
