MAX13223E

±70V Fault-Protected, 3.0V to 5.5V,

2Tx/2Rx RS-232 Transceiver

General Description

Beneﬁts and Features

● Robust Protection to Withstand Load Dumps,

Miswiring, and Connector Failures

• ±70V Fault Protection

The MAX13223E is a +3.0V to +5.5V-powered EIA/TIA-232

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.

• Overvoltage Current Limiting

• Current Protection at Transmitter Outputs

• Thermal Shutdown Protection

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,

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.

● Flexible Power Requirements Simplify Design

• +3.0V to +5.5V Single Supply Voltage

• True RS-232 Performance (Up to 250kbps) Even

from +3.0V Supply Voltage

● AutoShutdown Simplifies Power Savings

• Automatically Enters Shutdown Mode if RS-232

Cable is Disconnected or Receivers are Inactive

Automatically Activates from Shutdown When Any

Valid Transition is Sensed

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.

• 1µA Typical Shutdown Current

Ordering Information

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 specified over the

-40°C to +85°C temperature range.
