Note: 1 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).
2 Output short circuit conditions must maintain the total power dissipation below absolute
maximum ratings.
3 Test conditions are those specified by EIA-232-E and as listed above.
VDD = 12 V, VSS = -12 V, VCC = 5 V, TA = 25 °C
