Key Features

  • Operates from a single 3.3 V supply with integrated charge pump generating ±5.4 V RS-232 compliant output levels without external power rails
  • Dual drivers and dual receivers with Schmitt-trigger inputs provide robust noise immunity in electrically harsh serial communication environments
  • Industry-standard 16-pin SOIC-150 mil package with RoHS-compliant lead-free finish for straightforward drop-in replacement of legacy RS-232 transceivers

Applications

MAX3232CSE+T is widely used in embedded systems, industrial PLCs, and consumer electronics requiring RS-232 serial communication from a 3.3 V logic supply without a separate ±12 V rail. It connects microcontrollers and FPGAs to legacy RS-232 equipment such as terminal servers, barcode scanners, and industrial sensors across cable distances up to 15 meters.

Frequently Asked Questions

What supply voltage does MAX3232CSE+T require and how does it generate RS-232 voltage levels?

MAX3232CSE+T operates from a single 3.3 V supply and uses an internal charge pump with four small external capacitors (typically 100 nF each) to produce ±5.4 V RS-232-compliant driver output levels, eliminating the need for a dual-polarity power supply.

How many RS-232 channels does the MAX3232CSE+T support in a single 16-pin SOIC package?

The MAX3232CSE+T integrates 2 RS-232 driver channels and 2 receiver channels in one 16-pin SOIC-150 mil package, making it ideal for microcontroller serial port interfaces where space is limited and 2-wire RS-232 communication is needed.

When should a designer choose MAX3232CSE+T over MAX232 for a new RS-232 interface design?

MAX3232CSE+T is preferred over MAX232 in any 3.3 V system because MAX232 requires a 5 V supply and cannot be powered directly from modern low-voltage MCU rails. The MAX3232 supports 3.3 V operation with the same 4-capacitor charge pump topology, data rates up to 120 kbps, and drop-in pin compatibility for easy migration.
