Rꢁꢂ232 Transceivers in UCꢁ- and WL-  
0/MX231AE  
General Description  
Features  
♦ 6 x 5 Chip-Scale Package (UCSP) and WLP  
The MAX3230E/AE and MAX3231E/AE are +2.5V to  
+5.5V powered EIA/TIA-232 and V.28/V.24 communica-  
tions interfaces with low power requirements, high data-  
rate capabilities, and enhanced electrostatic discharge  
(ESD) protection, in a chip-scale package (UCSP™)  
and WLP package. All transmitter outputs and receiver  
inputs are protected to 15kV using IEC 1000-4-2 Air-  
Gap Discharge, 8kV using IEC 1000-4-2 Contact  
Discharge, and 15kV using the ꢀuman ꢁodꢂ Model.

♦ ±µꢂ Low-Power ꢂHtoShHtdown  
♦ 251kbps ꢃHaranteed Data Rate  
♦ ꢇeet EIꢂ/TIꢂ-232 Specifications Down to +3.±ꢀ  
The MAX3230E/AE and MAX3231E/AE achieve a 1µA  
supplꢂ current with Maxim’s AutoShutdown™ feature.  
Theꢂ save power without changing the existing ꢁIOS or  
operating sꢂstems bꢂ entering low-power shutdown  
mode when the RS-232 cable is disconnected, or when  
the transmitters of the connected peripherals are off.  
♦ RS-232 Coupatible to +2.5ꢀ ꢂllows Operation  
frou Single Li+ Cell  
♦ Suall 1.±µF Capacitors  
♦ ConfigHrable Logic Levels  
Ordering Information  
The transceivers have a proprietarꢂ low-dropout trans-  
mitter output stage, delivering RS-232-compliant perfor-  
mance from a +3.1V to +5.5V supplꢂ, and RS-232-  
compatible performance with a supplꢂ voltage as low  
as +2.5V. The dual charge pump requires onlꢂ four,  
small 0.1µF capacitors for operation from a +3.0V sup-  
plꢂ. Each device is guaranteed to run at data rates of  
250kbps while maintaining RS-232 output levels.
