DESCRIPTION/ORDERING INFORMATION  
The TRS3237E consists of five line drivers, three line receivers, and a dual charge-pump circuit with ±15-kV  
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 250 kbit/s in normal operating mode  
(MBAUD = GND) and 1Mbit/s when MBAUD = VCC. The driver output slew rate is a maximum of 30 V/μs.  
The TRS3237E transmitters are disabled and the outputs are forced into high-impedance state when the device  
is in shutdown mode (SHDN = GND) and the supply current falls to less than 1 μA. Also, during shutdown, the  
onboard charge pump is disabled; V+ is lowered to VCC, and V– is raised toward GND. Receiver outputs also  
can be placed in the high-impedance state by setting enable (EN) high. ROUT1B remains active all the time,  
regardless of the EN and SHDN condition.  
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.  
UNLESS OTHERWISE NOTED this document contains  
Copyright © 2007, Texas Instruments Incorporated  
PRODUCTION DATA information current as of publication date.  
Products conform to specifications per the terms of Texas  
Instruments standard warranty. Production processing does not  
necessarily include testing of all parameters.
