MAX3232CPE 3V5V RS232
Transceiver MAX3232CPE

The MAX3232CPE has a
proprietary low-dropout
transmitter stage
enabling true RS232
performance from 3V to
5.5Vdc supplies. The
internal power supply
consists of a regulated
dual charge pump that
produces output voltages
of 5.5V and -5.5V from an
input voltage range of 3V
to 5.5V. Requiring only
four 0.1microF external
capacitors for use with
the charge pump circuitry
the device is guaranteed
to run at data rates of
120kps while maintaining
RS232 output levels. The
MAX3232CPE has two
receivers and two drivers
and is ideal for 3.3V
systems mixed 3.3V5V
systems or 5V systems
that require true RS232
performance. The device
consumes only 250microA
has a 4Vmicros slew rate
and is pin and
functionally compatible
with the industry
standard MAX232.
Applications include
computers notebooks
palmtops battery powered
equipment hand-held
equipment and
peripherals. Supplied in
an 18-pin DIL package.

MAX233CPP 5V Powered RS-232
DriverReceiver MAX233CPP

The MAX233 is a 2-line
driverreceiver IC
intended for all
EIATIA-232E and V.28V.24
communication interfaces
especially where no
plusmn12V supply is
available. The device
includes on-board voltage
convertors that require
no external capacitors
which makes the IC
suitable for
battery-powered systems
and applications where
PCB space is critical.
Data transfer rate is
120kbps. Supplied in a
20-pin
DILpackage.Specifications

MAX232CPE
RS-232TransmitterReceiver
MAX232CPE

A dual RS-232
receivertransmitter that
meets all the EIA RS-232C
specifications while
requiring only a single
5V supply. This
significantly simplifies
system design by removing
the need to provide power
supply voltages other
than 5V. The IC has two
on-board charge pump
voltage convertors which
generate 10V and -10V
power supplies from the
single 5V supply.The IC
contains four level
translators two of which
convert TTLCMOS input
levels into plusmn9V
RS-232 outputs ready for
transmission and two of
which convert RS-232
inputs to 5V TTLCMOS
levels. The receivers
have a nominal threshold
of 1.3V a typical
hysteresis of 0.5V and
can operate with up to
plusmn30V inputs.

MAX202 RS232 Transceivers
MAX202CPE

The MAX202 transceiver is
designed for RS232 and
V.28 communication
interfaces where a
plusmn12V supply is not
available. On-board
charge pumps convert the
5V input to the plusmn10V
needed for RS232 output
levels. The drivers and
receivers meet all
EIATIA-232E and CCITTV.28
specifications at a data
rate of 20kbitssec. The
device requires just four
external capacitors to
provide the voltage
conversion. Supplied in a
16-pin DIL package
MAX202CPE.
