DESCRIPTION/ORDERING INFORMATION  
The TRS3243E device consists of three line drivers, five line receivers, and a dual charge-pump circuit with  
±15-kV ESD (HBM and IEC61000-4-2, Air-Gap Discharge) and ±8-kV ESD (IEC61000-4-2, Contact Discharge)  
protection on serial-port connection pins. 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. This  
combination of drivers and receivers matches that needed for the typical serial port used in an IBM PC/AT, or  
compatible. The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V  
supply. In addition, the device includes an always-active noninverting output (ROUT2B), which allows  
applications using the ring indicator to transmit data while the device is powered down. The device operates at  
data signaling rates up to 250 kbit/s and a maximum of 30-V/µs driver output slew rate.  
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.
