Transceivers for -DAs and Cell -hones  
General Description  
Features  
The MAX3388E/MAX3389E are 2.5V-powered EIA/TIA-  
232 and V.28/V.24 communications interfaces with low  
power requirements, high data-rate capabilities, and  
enhanced electrostatic discharge (ESD) protection. The  
MAX3388E/MAX3389E have two receivers and three  
transmitters. All RS-232 inputs and outputs are protected  
to ±±5ꢀV using the IEꢁ ±111-4-2 Air-ꢂap Discharge  
method, ±8ꢀV using the IEꢁ ±111-4-2 ꢁontact Discharge  
method, and ±±5ꢀV using the ꢃuman ꢄodꢅ Model.

In addition to the traditional RS-232 I/O, these devices have  
dedicated logic-level I/O pins for additional device-to-  
device handshaꢀing. During shutdown the logic-level I/O  
pins are active for the MAX3389E. An internal 62Ω switch is  
provided to switch power to external circuitrꢅ or modules.

OUꢅ  
A proprietarꢅ low-dropout transmitter output stage  
enables RS-232 compatible performance from a +2.35V  
to +3.1V supplꢅ with a dual charge pump. The charge  
pump requires onlꢅ four small 1.±µF capacitors for oper-  
ation from a +2.5V supplꢅ. The MAX3388E/MAX3389E  
are capable of running at data rates up to 461ꢀbps while  
maintaining RS-232-compatible output levels.

Peripherals  
The MAX3388E/MAX3389E have a unique V pin that
