The MAX13223E is a +3.0V to +5.5V-powered EIA/TIA-

232 and V.28 communications interface with fault protec-

tion on the RS-232 line interface. This allows shorts of the

transmitter outputs and receiver inputs to voltages in the

±70V range without adversely affecting the MAX13223E.

The MAX13223E achieves 1µA supply current using

Maxim’s AutoShutdown™ feature. The MAX13223E

automatically enters a low-power shutdown mode when

the RS-232 cable is disconnected or the receivers are

inactive. The device turns on again when a valid transi-

tion at any receiver input is sensed. A proprietary, high-

efficiency, dual charge-pump power supply and a

low-dropout transmitter combine to deliver true RS-232

performance from a single +3.0V to +5.5V supply.

The MAX13223E has two receivers and two drivers and is

guaranteed to run at data rates of 250kbps for one trans-

mitter switching while maintaining RS-232 output levels.

The MAX13223E operates from input voltages ranging

from +3.0V to +5.5V and is available in a 20-pin, 6.5mm

x 4.4mm, TSSOP package. The MAX13223E is speci-

fied over the -40°C to +85°C temperature range.
