AC ELECTRICAL CHARACTERISTICS

(Commercial: VCC = 5V ± 10%, TA = 0

°C to +70°C; Industrial: VCC = 5V ± 10%, TA = –40°C to +85°C)

NOTES:

1. Industrial temperature range product for 15ns and 25ns speed grade are available as a standard device.

2. Pulse widths less than minimum values are not allowed.

3. Values guaranteed by design, not currently tested.
