(1) The maximum total current, I(OHmax), for all outputs combined should not exceed ±20 mA to hold the maximum voltage drop specified.
See Recommended Operating Conditions for more details.
(2) The maximum total current, I(OLmax), for all outputs combined should not exceed ±48 mA to hold the maximum voltage drop specified.
(3) The maximum total current, I(OLmax), for all outputs combined should not exceed ±100 mA to hold the maximum voltage drop specified.

(1) A resistive divider with 2 × R1 between VCC and VSS is used as load. The output is connected to the center tap of the divider. For full
drive strength, R1 = 550 Ω. For reduced drive strength, R1 = 1.6 kΩ. CL = 20 pF is connected to the output to VSS.
(2) The output voltage reaches at least 10% and 90% VCC at the specified toggle frequency.
