GENERAL DESCRIPTION  
Emissions are also controlled to within very strict limits. CMOS  
technology is used to keep the power dissipation to an absolute  
minimum, allowing maximum battery life in portable applications.  
The ADM3232E transceiver is a high speed, 2-channel RS-232/V.28  
interface device that operates from a single 3.3 V power supply.  
Low power consumption makes it ideal for battery-powered  
portable instruments. The ADM3232E conforms to the EIA-232E  
and ITU-T V.28 specifications and operates at data rates up to  
460 kbps.  
Four external 0.± μF charge pump capacitors are used for the  
voltage doubler/inverter, permitting operation from a single  
3.3 V supply.  
All RS-232 (TxOUT and RxIN) inputs and outputs are protected  
against electrostatic discharges (up to ±±1 kV ESD protection).  
This ensures compliance with IEC ±000-4-2 requirements.  
The ADM3232E is available in a ±6-lead narrow and wide SOIC  
packages, as well as a space-saving ±6-lead TSSOP.  
This device is ideally suited for operation in electrically harsh  
environments or where RS-232 cables are frequently plugged/  
unplugged, with the ±±1 kV ESD protection of the ADM3232E  
RS-232 input/output pins.
