19-1604; Rev 0; 1/00 ±15kV ESD-Protected, 1Mbps, 1µA RS-232 Transmitters in SOT23-6 General Description The MAX3188E/MAX3189E 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 150µA of supply current from ±4.5V to ±6V 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 data transm.

19-1604; Rev 0; 1/00 ±15kV ESD-Protected, 1Mbps, 1µA RS-232 Transmitters in SOT23-6 General Description The MAX3188E/MAX3189E 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 150µA of supply current from ±4.5V to ±6V 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 data transmission is guaranteed up to 250kbps with the MAX3188E and up to 1Mbps with the MAX3189E. The MAX3188E/MAX3189E are EIA/TIA-232 transmitters that convert CMOS/TTL logic levels to RS-232-compliant signals. The transmitter output is protected to ±15kV using the IEC 1000-4-2 Air-Gap Discharge method, to ±8kV using the IEC 1000-4-2 Contact Discharge method, and to ±15kV per the Human Body Model, ensuring strict compliance with international standards. The MAX3188E/MAX3189E transmitters have a standard inverting output. o Small 6-Pin SOT23 Package o ESD-Protected RS-232 Output ±15kV per Human Body Model ±8kV per IEC 1000-4-2, Contact Discharge ±15kV per IEC 1000-4-2, Air-Gap Discharge o 150µA Operating Supply Current o Shutdown Reduces Supply Current to 1µA o Guaranteed Data Rate 1Mbps (MAX3189E) 250kbps (MAX3188E) o Three-State RS-232 Transmitter Output o No External Components Features MAX3188E/MAX3189E Applications Diagnostic Ports Telecommunications Networking Equipment Set-Top Boxes Digital Cameras Hand-Held Equipment PART MAX3188EEUT-T MAX3189EEUT-T Ordering Information TEMP.

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.
