Electrical Characteristics (Continued)

Note 8: QA outputs are tested at IOL = Max plus the limit value of IIL for the B input. This permits driving the B input while maintaining full fan-out capability.

Note 9: Not more than one output should be shorted at a time, and the duration should not exceed one second.

Note 10: ICC is measured with all outputs open, both RO inputs grounded following momentary connection to 4.5V and all other inputs grounded.
