How many amperes of current can an output pin drive?

It is defined as output current, IOUT, in the Absolute Maximum Ratings table, which is the maximum limit per output.

The following table shows the absolute rated output current, IOUT, and DC Vcc/ground current, Icc, of the 74xxx244 (In the case of One-Gate logic 125 or 126 type.). The DC Vcc/ground current, Icc, is the maximum current per IC. The sum of the currents that flow through eight outputs must not exceed Icc.
