3 Description

The SN65C3243 and SN75C3243 consist of three

line drivers, five line receivers, and a dual chargepump

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.
