MAX3190-MAX3190E Datasheet, PDF (1/8 Pages) Maxim Integrated Products – ±15kV ESD-Protected, 460kbps, RS-232 Transmitters in SOT23-6

19-1931; Rev 1; 3/03
±15kV ESD-Protected, 460kbps,
RS-232 Transmitters in SOT23-6
General Description
The MAX3190/MAX3190E single RS-232 transmitters in
a SOT23-6 package are for space- and cost-con-
strained applications requiring minimal RS-232 commu-
nications. These devices consume only 200µA of
supply current from ±7.5V to ±12V supplies. The
MAX3190/MAX3190E transmitter outputs are RS-232
compatible when powered from ±6V to ±7.5V supplies.
They feature a shutdown input that reduces current
consumption to only 1µA and forces the transmitter out-
put into a high-impedance state. RS-232-compliant data
transmission is guaranteed up to 460kbps.
The MAX3190/MAX3190E are EIA/TIA-232 transmitters
that convert CMOS/TTL logic levels to RS-232-compliant
signals. The MAX3190E transmitter output is protected
to ±15kV per the Human Body Model, ±8kV per IEC
1000-4-2 Contact Discharge, and ±15kV per IEC 1000-
4-2 Air-Gap Discharge, providing protection against
harsh environments. The MAX3190/ MAX3190E trans-
mitters have a standard inverting output.
