1ꢀ5k EꢁDꢂ-rotected, 4605bps,
Rꢁꢂ232 Transmitters in ꢁOT23ꢂ6
General Description
Features
The MAX3190/MAX3190E 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 200µA of
supply current from ±±.ꢀ5 to ±125 supplies. The
MAX3190/MAX3190E transmitter outputs are RS-232
compatible when powered from ±65 to ±±.ꢀ5 supplies.
They feature a shutdown input that reduces current
consumption to only 1µA and forces the transmitter out-
put into a high-impedance state. RS-232-compliant data
transmission is guaranteed up to 460kbps.

Supplieꢈ
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 ±1ꢀk5 per the ꢁuman ꢂody Modelꢃ ±ꢄk5 per IEC
1000-4-2 Contact Dischargeꢃ and ±1ꢀk5 per IEC 1000-
4-2 Air-Gap Dischargeꢃ providing protection against
harsh environments. The MAX3190/ MAX3190E trans-
mitters have a standard inverting output.
