MAX3232 Datasheet PDF – RS-232 Line Driver/Receiver – TI

Part Number: MAX3232, MAX3232IDW

Function: 3-V to 5.5-V Multichannel RS-232 Line Driver/Receiver

Package: SOIC, SSOP, TSSOP 16 Pin type

Manufacturer: Texas Instruments




The MAX3232 is a low-power transceiver that is used for converting voltage levels between RS-232 and TTL/CMOS interfaces. It is commonly used for communication between a microcontroller or a computer and serial devices such as printers, modems, or sensors. The device provides a simple, low-cost solution for serial communication and it has a high data rate of up to 250 kbps. It is also capable of operating over a wide range of supply voltages, making it suitable for a wide range of applications.

The MAX3232 device consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD protection terminal to terminal (serial-port connection terminals, 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. The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V supply. The devices operate at data signaling rates up to 250 kbit/s and a maximum of 30-V/μs driver output slew rate.
