0V to 5.
5V, 2Tx/2Rx RS-232 Transceiver General Description The MAX13223E is a +3.
0V to +5.
5V-powered EIA/TIA232 and V.
28 communications interface with fault protection 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 transition at any receiver input is sensed.
A proprietary, highefficiency, 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 transmitter 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.
