GENERAL DESCRIPTION  
0.1µF  
10V  
The ADM3202/ADM3222/ADM1385 transceivers are high  
speed, 2-channel RS-232/V.28 interface devices that operate  
from a single 3.3 V power supply. Low power consumption and  
a shutdown facility (ADM3222/ADM1385) make them ideal for  
battery-powered portable instruments.

ON EACH RS-232 INPUT  
Four external 0.1 μF charge pump capacitors are used for the  
voltage doubler/inverter, permitting operation from a single  
3.3 V supply.

The ADM3202 is available in a 16-lead PDIP, SOIC_W, and  
SOIC_N, as well as a space-saving 16-lead TSSOP. The ADM3222  
is available in 18-lead PDIP and SOIC_W and in 20-lead SSOP  
and TSSOP. The ADM1385 is available in a 20-lead SSOP,  
which is pin-compatible with the LTC1385 CG.
