GENERAL DESCRIPTION
The ADM202/ADM203 is a two-channel RS-232 line driver/
receiver pair designed to operate from a single 5 V power sup-
ply. A highly efficient on-chip charge pump design permits
RS-232 levels to be developed using charge pump capacitors as
small as 0.1 µF. The capacitors are internal to the package on
the ADM203 so no external capacitors are required. These
converters generate ± 10 V RS-232 output levels.
The ADM202/ADM203 meets or exceeds the EIA-232-E and
V.28 specifications. Fast driver slew rates permit operation up to
120 kB while high-drive currents allow for extended cable lengths.
An epitaxial BiCMOS construction minimizes power consump-
tion to 10 mW and also guards against latch-up. Overvoltage
protection is provided allowing the receiver inputs to withstand
continuous voltages in excess of ± 30 V. In addition, all pins
contain ESD protection to levels greater than 2 kV.
The ADM202 is available in 16-lead DIP and both narrow and
wide SOIC packages. The ADM203 is available in a 20-lead
DIP package.
