MAX231MJD

Overview

The MAX231MJD is a +5V-powered, multichannel RS-232 driver and receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within the -40°C to +85°C temperature range and utilizes a 16-pin Wide SOIC package. The device provides two drivers and two receivers for full-duplex communication with a data rate of up to 120 kbps. It requires four external capacitors (C1–C4) for its internal charge pump circuitry, which generates the necessary ±10V levels from a single +5V supply.

Feature Summary

Integrates dual charge-pump DC-DC voltage converters to generate required RS-232 voltage swings from a single +5V source
Eliminates the need for an external bipolar ±12V power supply in standard EIA/TIA-232E applications
Provides TTL/CMOS-compatible inputs and outputs for direct interfacing with microcontrollers and UARTs

Applications

Interface translation between TTL/CMOS logic and RS-232 serial ports
Multidrop RS-232 network connections
Portable diagnostic equipment requiring serial communication

Procurement Notes

Verify the specific suffix 'MJD' against the manufacturer's current ordering information table to confirm the exact package type and temperature grade. Ensure that the required external capacitors are included in the bill of materials, as they are not integrated internally for this specific part number variant.

Selection Notes

Select this component when designing systems that require RS-232 connectivity but are constrained to a single +5V power rail. It is suitable for industrial environments operating between -40°C and +85°C. Compare pin counts and channel availability against other family members like the MAX232 or MAX241 if additional drivers or receivers are needed.

Part Context

This component belongs to the MAX220–MAX249 family of +5V-powered multichannel RS-232 drivers and receivers. The family offers various configurations of drivers and receivers across multiple package types and temperature ranges to accommodate different board space and interface requirements.
