V
Driver electrical characteristics over operating free-air temperature range
The algebraic convention, where the more positive (less negative) limits designated as
maximum, is used in this datasheet for logic levels only (e.g. if - 10 V is a maximum, the
typical value is a more negative voltage).
Output short circuit conditions must maintain the total power dissipation below absolute
maximum ratings.
Test conditions are those specified by EIA-232-E and as listed above.
V
Driver switching characteristics
Measured between -3 V and 3 V points of output waveform (EIA-232-E conditions), all
unused inputs are tied.
