AC ELECTRICAL CHARACTERISTICS(1) (Continued)
(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. Military speed grades of 50ns and 80ns are only available for IDT7201LA.
3. Pulse widths less than minimum value are not allowed.
4. Values guaranteed by design, not currently tested.
5. Only applies to read data flow-through mode.
