MAXIM MAX3190, MAX3190E Technical data

General Description

The MAX3190/MAX3190E single RS-232 transmitters in
a SOT23-6 package are for space- and cost-con­strained applications requiring minimal RS-232 commu­nications. 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 out­put 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 1000­4-2 Air-Gap Discharge, providing protection against
harsh environments. The MAX3190/ MAX3190E trans­mitters have a standard inverting output.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
