MAX3221IPW

Overview

The MAX3221IPWR is a single-channel RS-232 line driver and receiver manufactured by Texas Instruments. It operates from a single 3V to 5.5V power supply and includes internal charge pumps to generate the required voltages for RS-232 communication without external components. The device supports data rates up to 250kbps and features a 500mV hysteresis on the receiver input to improve noise immunity. It is housed in a 16-pin TSSOP package and is rated for operation over an extended temperature range of -40°C to +85°C.

Feature Summary

Integrates dual charge pumps to eliminate the need for external voltage conversion capacitors
Provides full-duplex communication capability with one driver and one receiver channel
Features Schmitt-trigger receiver inputs with 500mV hysteresis for enhanced signal integrity

Applications

Industrial control systems requiring robust serial communication
Portable instrumentation and battery-powered devices
Modem and communications equipment interfaces

Procurement Notes

Verify the specific suffix (e.g., IPWR) against the official datasheet to confirm the package type and temperature rating. Ensure that ordering information matches the exact component designation to avoid discrepancies in electrical specifications or physical dimensions during procurement.

Selection Notes

Select this component when a single-channel RS-232 interface is needed with low power consumption and minimal external component count. It is suitable for designs operating within the 3V to 5.5V range where space constraints favor the TSSOP-16 package over larger alternatives.

Part Context

This part belongs to the MAX3221 family of RS-232 transceivers designed for low-power applications. It serves as a direct replacement for older generations of RS-232 drivers that require multiple external capacitors, simplifying board layout and reducing overall system cost while maintaining compatibility with standard RS-232 protocols.
