DESCRIPTION/ORDERING INFORMATION  
The MAX3227E consists of one line driver, one line receiver, and a dual charge-pump circuit with ±15-kV IEC  
ESD protection pin to pin (serial-port connection pins, including GND). The device meets the requirements of  
TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the  
serial-port connector. The charge pump and four small external capacitors allow operation from a single 3-V to  
5.5-V supply. This device operates at data-signaling rates of 1 Mbit/s in normal operating mode and a maximum  
of 30-V/µs driver output slew rate. This device also features a logic-level output (READY) that asserts when the  
charge pump is regulating and the device is ready to begin transmitting.  
The MAX3227E achieves a 1-µA supply current using the auto-powerdown plus feature. This device  
automatically enters a low-power powerdown mode when the RS-232 cable is disconnected or the drivers of the  
connected peripherals are inactive for more than 30 s. They turn on again when they sense a valid transition at  
any driver or receiver input. Auto-powerdown saves power without changes to the existing BIOS or operating  
system.  
The MAX3227EC is characterized for operation from 0°C to 70°C. The MAX3227EI is characterized for operation  
from –40°C to 85°C.
