+3.0V to +5.5V, 1µA, up to 250kbps, True  
RS-232 Transceiver with AutoShutdown Plus  
_______________General Description  
____________________________Features  
The MAX3238 true RS-232 transceiver achieves a  
1µA supply current with Maxim’s revolutionary  
AutoShutdown Plus™ feature. When the device does  
not sense a valid signal transition on either the receiver  
or transmitter inputs within 30sec, the on-board power  
supply and drivers shut down. This occurs if the RS-232  
cable is disconnected or if the transmitters of the con-  
nected peripheral are inactive. The system turns on  
again when a valid transition is applied to any RS-232  
receiver or transmitter input, saving power without  
changes to the existing BIOS or operating system.  
ꢀ 1µA Supply Current Achieved with  
AutoShutdown Plus  
ꢀ Guaranteed Data Rate: 250kbps  
ꢀ 1µA Low-Power Shutdown  
ꢀ Receivers Active in AutoShutdown Plus Mode  
ꢀ Flow-Through Pinout  
ꢀ Meets EIA/TIA-232 Specifications Down to 3.0V  
ꢀ Guaranteed 6V/µs Slew Rate  
The MAX3238 5-driver/3-receiver complete serial port is  
a 3V-powered EIA/TIA-232 and V.28/V.24 communica-  
tions interface intended for notebook or subnotebook  
computer applications. 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. A guaranteed  
data rate of 250kbps provides compatibility with popu-  
lar software for communicating with personal comput-  
ers. The MAX3238 requires only 0.1µF capacitors in  
3.3V operation. It is ideal for 3.3V-only systems, mixed  
3.3V and 5.0V systems, or 5V-only systems that require  
true RS-232 performance.
