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
μ
F. The capacitors are internal to the package on
the ADM203 so no external capacitors are required. These con-
verters 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 allows 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-pin DIP
package.
