MAX13223E - 2Tx/2Rx RS-232 Transceiver

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.

19-4585; Rev 0; 4/09 www.DataSheet4U.com ±70V Fault-Protected, 3.0V 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.
