NOTES:
1. Stresses greater than those listed under ‘Absolute Maximum Ratings’ may cause
permanent damage to the device. This is a stress rating for transient conditions only.
Functional operation of the device at these or any other conditions outside those indicated
in the ‘Operating Range’ of this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
2. Outputs should not be shorted for more than 30 seconds. No more than one output should be
shorted at any time.
3. Negative undershoot of 1.5 V in amplitude is permitted for up to 10 ns, once per cycle.

NOTES:
1. ICC, ICC2, ICC3, and ICC4 are dependent upon actual output loading, and ICC and ICC4 are also dependent on cycle rates. Specified values are
with outputs open (for ICC: CL = 0 pF); and, for ICC and ICC4, operating at minimum cycle times.
2. ICC (MAX.) using worst case conditions and data pattern. ICC (TYP.) using VCC = 5 V and and ‘average’ data pattern.
3. ICC2 (TYP.) and ICC4 (TYP.) using VCC = 5 V and TA = 25°C.
