1Mbps, 1µA RS-232 Transmitters in SOT23-6
General Description
The MAX3188/MAX3189 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. RS-232 data transmission
is guaranteed up to 250kbps with the MAX3188 and up
to 1Mbps with the MAX3189.
The MAX3188/MAX3189 transmitters are inverting level
translators that convert CMOS-logic levels to 5V
EIA/TIA-232 levels. They feature a shutdown input that
reduces current consumption to only 1µA and forces
the transmitter output into a high-impedance state. The
MAX3188/MAX3189 transmitters have a standard
inverting output.
