Guaranteed Data Rate The MAX3188E/MAX3189E are EIA/TIA-232 transmitters 1Mbps (MAX3189E) that convert CMOS/TTL logic levels to RS-232-compliant 250kbps (MAX3188E) signals. The transmitter output is protected to 15kV Three-State RS-232 Transmitter Output using the IEC 1000-4-2 Air-Gap Discharge method, to 8kV using the IEC 1000-4-2 Contact Discharge No External Components method, and to 15kV per the Human Body Model, ensuring strict compliance with international standards. The MAX3188E/MAX3189E transmitters have a standard inverting output. Applications Ordering Information Diagnostic Ports PIN- TOP PART TEMP.

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. ELECTRICAL CHARACTERISTICS (V = +4.5V to +6V, V = -4.5V to -6V, T = T to T , unless otherwise noted.
