The CT3232 Driver section accepts complementary TTL Data at the input, and produces a 30 Volt nominal peak-to-peak differential signal across a 140 load at the output. When coupled to the Data Bus with a 1:1 transformer, isolated on the Data Bus side with two 55.0 fault isolation resistors, and loaded by two 70 terminations plus additional receivers, the Data Bus signal produced is 7.2 Volts nominal peak-to-peak. When both "DATA" and "DATA" inputs are held low or both are held high, the driver output becomes a high impedance and is "removed" from the line. In addition, an overriding "INHIBIT" input provides for removal of the Driver output from the line. A logic "1" applied to the "INHIBIT" takes priority over the condition of the data inputs and disables the Driver. See Driver Logic Waveforms, Figure 3.
