MAX3190/MAX3190E 19-1931 Rev 1 3/03 15kV ESD-Protected, 460kbps, RS-232 Transmitters in SOT23-6 General Description Features The MAX3190/MAX3190E single RS-232 transmitters in Small 6-Pin SOT23 Package a SOT23-6 package are for space- and cost-con- ESD-Protected RS-232 Output (MAX3190E) strained applications requiring minimal RS-232 commu- 15kV per Human Body Model nications. These devices consume only 200A of supply current from 7.5V to 12V supplies. The 8kV per IEC 1000-4-2 Contact Discharge MAX3190/MAX3190E transmitter outputs are RS-232 15kV per IEC 1000-4-2 Air-Gap Discharge compatible when powered from 6V to 7.5V supplies. 200A Operating Supply Current They feature a shutdown input that reduces current Shutdown Reduces Supply Current to 0.4A consumption to only 1A and forces the transmitter out- put into a high-impedance state. RS-232-compliant data RS-232-Compliant Operation from 7.5V to 12V transmission is guaranteed up to 460kbps. Supplies The MAX3190/MAX3190E are EIA/TIA-232 transmitters RS-232-Compatible Operations from 6V to 7.5V that convert CMOS/TTL logic levels to RS-232-compliant Supplies signals. The MAX3190E transmitter output is protected to 15kV per the Human Body Model, 8kV per IEC 460kbps Guaranteed Data Rate 1000-4-2 Contact Discharge, and 15kV per IEC 1000- Three-State RS-232 Transmitter Output 4-2 Air-Gap Discharge, providing protection against harsh environments. The MAX3190/ MAX3190E trans- No External Components mitters have a standard inverting output.

CC EE 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.
