NOTES:

1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the

device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to

absolute-maximum-rated conditions for extended periods may affect device reliability.

2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction

temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.

3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

NOTES:

1. Not more than one output should be tested at a time, and the duration of the test should not exceed one second.

2. This is the increase in supply current for each input at 3.4V.

3. For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power.

4. This parameter is valid for any V

between 0V and 2.1V with a transition time of up to 10msec. From V

= 2.1V to V

= 5V ± 10% a

transition time of up to 100µsec is permitted.

5. Unused pins at V

or GND.

6. This is the bus hold overdrive current required to force the input to the opposite logic state.
