DESCRIPTION
The DS229 is a triple 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 DS229 uses on–board charge pumps
to convert the +5 volt supply to
±
10 volts. The DS229 is
fully compliant with EIA RS–232E and V.28/V.24 stan-
dards. The DS229 contains three drivers and three
receivers. Driver slew rates and data rates are guaran-
teed up to 116 kbits/sec. The DS229 operates with only
0.1
μ
F charge pump capacitors.
OPERATION
The diagram in Figure 1 shows the main elements of the
DS229. The following paragraphs describe the function
of each pin.
