MAX331CPE

Overview

The MAX331CPE is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, designed for EIA/TIA-232-F and V.28/V.24 communication interfaces. It operates from a single +5V supply with integrated charge pumps to generate ±6V levels. The device features two drivers and two receivers, supporting data rates up to 120kbps. It is housed in a 16-pin PDIP package and operates within a temperature range of 0°C to +70°C.

Feature Summary

Integrated charge pump eliminates the need for external capacitors
Single +5V power supply operation
Compliant with EIA/TIA-232-F standards

Applications

Modems
Portable instruments
Communications equipment

Procurement Notes

Verify the specific suffix 'CPE' against the manufacturer's current datasheet to confirm pinout and electrical characteristics. Check for RoHS compliance status as older Maxim parts may have different environmental declarations. Confirm availability through authorized distributors as this component may be subject to lifecycle changes.

Selection Notes

Select the MAX331CPE when a dual-channel RS-232 solution is required with minimal external components. Ensure the application voltage matches the +5V single-supply requirement. Consider the PDIP-16 package constraints for PCB layout if through-hole mounting is necessary. Verify that the 120kbps speed meets the system's baud rate requirements.

Part Context

The MAX331CPE belongs to the MAX331 family of low-power RS-232 transceivers. This series is characterized by its ability to operate from a single supply without requiring multiple voltage rails. It serves as a legacy interface component for serial communication systems requiring robust signal integrity over short distances.

Replacement Considerations

Direct replacements include the MAX321CPE or MAX3232CPE, depending on the required channel count and capacitor integration. Verify pin compatibility before substitution.
