description/ordering information  
The MAX3243consists of three line drivers, five line receivers, and a dual charge-pump circuit with 15-kV ESD  
(HBM) 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. 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.
