POINTS

NOTE: 6. Provide adequate decoupling capacitance as close as possible to this device to achieve the published A.C. and D.C. parameters.

A 0.1 microfarad capacitor in parallel with a 0.01 microfarad capacitor connected between VCC and ground is recommended.

Inadequate decoupling may result in access time degradation or other transient performance failures.

NOTES: 4. This parameter is only sampled and is not 100% tested.

5. Typical values are for TA = 25°C and nominal supply voltages.

A.C. testing inputs are driven at 3.0 V for a logic "1" and 0.0 V for a

logic "0." Timing measurements are made at 1.5 V for input and

output transitions in both directions.
