MAX3233EEPP

Overview

The MAX3233EEPP is a dual driver/receiver RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3V to +5.5V supply and supports data rates up to 120kbps. The device features full duplex communication with two drivers and two receivers. It includes internal charge pumps to generate the required RS-232 voltage levels from the single supply. The component is housed in a 20-pin Plastic Dual In-Line Package (PDIP) designed for through-hole mounting. It operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides true RS-232 signal transmission and reception using a single power supply
• Integrates charge pump circuitry to eliminate external high-voltage components
• Offers robust performance with guaranteed receiver hysteresis for noise immunity

Applications

• Industrial control systems requiring serial communication interfaces
• Point-of-sale terminals and barcode scanners
• Modem connections and portable instrumentation

Procurement Notes

Verify the specific suffix EEPP confirms the 20-PDIP package and extended temperature rating. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices or lifecycle status updates from the manufacturer before finalizing procurement plans.

Selection Notes

Select this part when a through-hole DIP solution is required for RS-232 connectivity. Ensure the design accommodates the necessary external capacitors for the internal charge pumps. Verify that the 120kbps speed meets system requirements compared to higher-speed alternatives like the MAX3232 series.

Part Context

This component belongs to the Maxim MAX323x family of low-power RS-232 transceivers. It shares functional similarities with other members like the MAX3232 but differs in pin count, package type, and specific electrical characteristics. The EEPP designation specifically identifies the extended temperature grade and PDIP packaging format within this product line.

Replacement Considerations

Direct pin-compatible replacements may include other MAX3233 variants with different packages such as SOIC or TSSOP. Cross-reference with MAX3232EPP if higher data rates are acceptable, noting differences in shutdown functionality and ESD protection specifications.
