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
V0.28/V0.24 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
μ
F charge pump capacitors.
OPERATION
The diagram in Figure 1 shows the main elements of the
DS232A. The following paragraphs describe the func-
tion of each pin.
