DESCRIPTION
The DS232A is a dual RS-232 driver/receiver pair that generates RS-232 voltage levels from a single +5-
volt power supply. Additional ±12-volt supplies are not needed since the DS232A uses on-board charge
pumps to convert the +5-volt supply to ±10 volts. The DS232A is fully compliant with EIA RS-232E and
V.28/V.24 standards. The DS232A contains two drivers and two receivers. Driver slew rates and data
rates are guaranteed up to 250k bits/sec. The DS232A operates with only 0.1 μF charge pump capacitors.
OPERATION
The diagram in Figure 1 shows the main elements of the DS232A. The following paragraphs describe the
function of each pin.
