General Description
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 1A 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.
