Notes: * VCC = 5 V, Ta = 25°C

** QA output is tested at specified IOL plus the limit value of IIL for the B input. This permits driving the B input

while maintaining full fan-out capability.

*** ICC is measured with all outputs open, both R0 inputs grounded following momentary connection to 4.5 V, and

all other inputs grounded.
