The MAX3188E/MAX3189E single RS-232 transmitters
in a SOT23-6 package are for space- and cost-con-
strained applications requiring minimal RS-232 commu-
nications. These devices consume only 150µA of
supply current from ±4.5V to ±6V supplies. They fea-
ture a shutdown input that reduces current consump-
tion to only 1µA and forces the transmitter output into a
high-impedance state. RS-232 data transmission is guar-
anteed 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.
