ST75185C Electrical characteristics
Doc ID 6228 Rev 18 7/22
V
DD
= 9 V, V
SS
= -9 V, V
CC
= 5 V, unless otherwise specified.
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.
V
DD
= 12 V, V
SS
= -12 V, V
CC
= 5 V, T
A
= 25 °C
4 Measured between -3 V and 3 V points of output waveform (EIA-232-E conditions), all
unused inputs are tied.
