pair adds 5 mA to I
the output load current should be multiplied by 1V instead of V
LOW, and outputs unloaded. I
current plus the sum of all the load currents for each output pin. The total buffer quiescent current is 10mA max., and max. TTL load current for each output pin can be calculated
as follows: Where R
account for worst process corner and temperature condition.
