±15 kV ESD Protected, 3.3 V, RS-232 Line Driver/Receiver
All RS-232 (T_OUT and R_IN) and TTL/CMOS (T_IN and R_OUT) inputs and outputs are protected against electrostatic discharges (up to ±15 kV ESD protection). This ensures compliance with IEC 1000-4-2 requirements.
This device is ideally suited for operation in electrically harsh environments or where RS-232 cables are frequently plugged/ unplugged, with the ±15 kV ESD protection of the ADM3232E input/output pins.
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.
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 ADM3232E is available in a 16-lead narrow SOIC package, as well as a space-saving 16-lead TSSOP.Applications
