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.
