WARNING:

Under no circumstance are negative undershoots, of any amplitude, allowed when device is in battery backup mode.

NOTES:

1. /WE is high for a read cycle.

going low to the earlier of /CEU, /CEL or /WE going high.

5. These parameters are sampled with a 5 pF load and are not 100% tested.

6. If the /CEU or /CEL low transition occurs simultaneously with or later than the /WE low transition in the output buffers

remain in a high impedance state during this period.

7. If the /CEU or /CEL high transition occurs prior to or simultaneously with the /WE high transition, the output buffers

remain in high impedance state during this period.

8. If /WE is low or the /WE low transition occurs prior to or simultaneously with the /CEU or /CEL low transition, the

output buffers remain in a high impedance state during this period.

10. All AC and DC electrical characteristics are valid over the full operating temperature range 0_C to 70_C.

11. In a power down condition the voltage on any pin may not exceed the voltage on Vcc .
