description/ordering information
The MAX3243 consists 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.
