MAX3221CPWRE4

Overview

The MAX3221CPWRE4 is a single-channel RS-232 line driver and receiver manufactured by Texas Instruments. It operates from a single 3-V to 5.5-V power supply and includes internal charge pumps to generate the required voltages for RS-232 communication without external inductors. The device features one driver and one receiver, supporting full-duplex data transmission at rates up to 250 kbps. It provides ±15-kV electrostatic discharge (ESD) protection on all RS-232 lines. The component is housed in a 16-pin TSSOP package and is designed for surface-mount installation.

Feature Summary

Integrated charge pump eliminates need for external inductors
High ESD protection rating on RS-232 lines
Single-supply operation with low standby current
AutoShutdown feature reduces power consumption

Applications

Portable equipment requiring RS-232 connectivity
Modems and fax machines
Handheld terminals and POS systems
Industrial control panels with serial interfaces

Procurement Notes

Verify the suffix RE4 indicates RoHS compliance and lead-free status as per Texas Instruments documentation. Confirm the CPW package code corresponds to the 16-TSSOP form factor. Ensure the C temperature grade matches the operational requirements of the target environment. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability.

Selection Notes

Select this component when a single RS-232 channel is sufficient for the application design. The MAX3221CPWRE4 is suitable for designs constrained by space due to its small TSSOP footprint. Consider the 250 kbps data rate limit against system requirements. Verify that the 3-V to 5.5-V supply range aligns with the available power rails in the host system.

Part Context

The MAX3221 belongs to the broader family of RS-232 transceivers produced by Texas Instruments and formerly Maxim Integrated. This specific variant integrates standard RS-232 functionality with enhanced ESD protection and low-power features. It serves as a direct replacement for legacy single-channel RS-232 drivers in modern embedded systems requiring reliable serial communication over short distances.

Replacement Considerations

The SN75C3221PWR is a pin-compatible alternative within the Texas Instruments portfolio offering similar single-channel RS-232 functionality. Designers should verify electrical parameter equivalence before substitution.
