MAX3232CSE+TG05

Overview

The MAX3232CSE+TG05 is a low-power, true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 3.0V to 5.5V supply and features two drivers and two receivers for full-duplex communication. The device utilizes an internal dual charge pump requiring only four 0.1µF external capacitors. It guarantees data rates up to 120kbps with worst-case loads of 3kΩ in parallel with 1000pF, while typical operation supports 235kbps. The component is housed in a 16-pin Narrow SO package and is designed for commercial temperature ranges.

Feature Summary

Proprietary low-dropout transmitter output stage enables true RS-232 performance from a single power supply.
Internal dual charge pump generates required voltage levels using only four small external capacitors.
Pin, package, and functionally compatible with the industry-standard MAX232 device.

Applications

Notebook, Subnotebook, and Palmtop Computers
High-Speed Modems
Battery-Powered Equipment

Procurement Notes

Verify the specific suffix 'G05' against official manufacturer documentation to confirm its exact meaning regarding packaging or testing variations. Confirm that the ordering information aligns with the standard MAX3232CSE+ part number structure provided in the datasheet. Ensure compatibility with the intended PCB footprint and soldering requirements for the Narrow SO package.

Selection Notes

Select this component when interfacing TTL/CMOS logic with RS-232 ports in space-constrained designs. It is suitable for applications requiring a single 3.0V to 5.5V supply without external high-voltage generation circuits. Consider the 120kbps guaranteed rate for standard PC-to-PC software compatibility, noting that higher speeds are possible under lighter loads.

Part Context

This part belongs to the MAX3222/MAX3232/MAX3237/MAX3241 family of low-power RS-232 transceivers. The MAX3232 variant specifically provides two drivers and two receivers, distinguishing it from the MAX3222 (with shutdown) and MAX3241 (five receivers). It serves as a direct replacement for legacy MAX232 designs while offering improved power efficiency and smaller external component counts.
