NOTES: 1. The supply current is the sum of ICC and IPP. The maximum current value is with Outputs O0 to O7 unloaded.
2. CMOS inputs: VIL = GND ± 0.3V, VIH = VCC ± 0.3 V.
*NOTICE:
Stresses above those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device.
This is a stress rating only and functional operation of
the device at these or any other conditions above
those indicated in the operational sections of this
specification is not implied. Exposure to absolute
maximum rating conditions for extended periods of
time may affect device reliability.
NOTE:
3. This parameter is only sampled and is not 100% tested. Output Float is defined as the point where data is no longer driven – see timing
diagram.
