Selecting reduced drive strength may reduce EMI.
(2)
The maximum total current, I(OHmax) and I(OLmax), for all outputs combined, should not exceed ±48 mA to hold the maximum voltage drop
specified.
(3)
The maximum total current, I(OHmax) and 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
. For reduced drive strength, R1 = 1.6 k. 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.
