±15kV ESD-Protected, 460kbps, RS-232 Transmitters in SOT23-6

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 1000-4-2 Air-Gap Discharge, providing protection against harsh environments. The MAX3190/ MAX3190E transmitters have a standard inverting output.
