MAX232D

Overview

The MAX232D is a dual driver/receiver RS-232 transceiver manufactured by Texas Instruments. It operates on a single +5V supply and includes internal charge pumps to generate the required voltages for EIA-232 compliance without external components. The device features two drivers and two receivers, supporting full-duplex communication at data rates up to 120 kb/s. It is housed in a 16-pin SOIC package and is rated for operation over an industrial temperature range of -40°C to +85°C.

Feature Summary

Integrated charge pump eliminates the need for external voltage generation capacitors.
Provides dual drivers and dual receivers for full-duplex serial communication.
Operates directly from a single +5V power supply.
Includes built-in ESD protection for enhanced signal integrity.

Applications

Connecting microcontrollers or DSPs to PC serial ports.
Industrial control systems requiring RS-232 connectivity.
Embedded systems with UART interfaces needing level shifting.

Procurement Notes

Verify the specific suffix 'D' indicates the industrial temperature grade (-40°C to +85°C) and SOIC package. Confirm RoHS compliance status through the official datasheet as manufacturing processes may vary. Check for obsolescence notices since this component has been in production for many years.

Selection Notes

Select the MAX232D when an industrial temperature range is required compared to the commercial MAX232DR variant. Ensure the design supports the 120 kb/s maximum data rate. Verify that the 16-pin SOIC footprint matches the PCB layout constraints.

Part Context

The MAX232 series is a legacy standard for RS-232 interface applications. The 'D' suffix specifically denotes the wide temperature operating range suitable for harsh environments. It serves as a bridge between TTL/CMOS logic levels and RS-232 voltage standards.

Replacement Considerations

MAX232ID: Industrial grade version in DIP package. TRS232D: Pin-compatible alternative with similar specifications. MAX3232: Higher speed (250 kb/s) and wider voltage support option.
