DESCRIPTION/ORDERING INFORMATION  
The TRSF3243 consists of three line drivers, five line receivers, and a dual charge-pump circuit with ±15-kV  
ESD protection pin to pin (serial-port connection pins, including GND). This device 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. In addition, this 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 1 Mbit/s and  
an increased slew-rate range of 24 V/μs to 150 V/μs.
