DESCRIPTION/ORDERING INFORMATION  
The MAX3318 is  
a dual-driver, dual-receiver, RS-232 compatible transceiver. The device features  
auto-power-down plus and enhanced electrostatic discharge (ESD) protection integrated into the chip. Driver  
output and receiver input are protected to ±8 kV using the IEC 61000 Air-Gap Discharge method, ±8 kV using  
the IEC 61000 Contact Discharge method, and ±15 kV using the Human-Body Model (HBM).  
The device operates at a data rate of 460 kbps. The transceiver has a proprietary low-dropout driver output stage  
enabling RS-232-compatible operation from a 2.25-V to 3-V supply with a dual charge pump. The charge pump  
requires only four 0.1-µF capacitors and features a logic-level output (READY) that asserts when the charge  
pump is regulating and the device is ready to begin transmitting.  
The MAX3318 achieves a 1-µA supply current using the auto-power-down feature. This device automatically  
enters a low-power power-down mode when the RS-232 cable is disconnected or the drivers of the connected  
peripherals are inactive for more than 30 s. The device turns on again when it senses a valid transition at any  
driver or receiver input. Auto power down saves power without changes to the existing BIOS or operating  
system.  
This device is available in two space-saving packages: 20-pin SSOP and 20-pin TSSOP.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas  
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.  
PRODUCTION DATA information is current as of publication date.

Instruments standard warranty. Production processing does not  
necessarily include testing of all parameters.
