MAX3222EIPW

Overview

The MAX3222EIPW is a dual-channel RS-232 transceiver manufactured by Texas Instruments, designed for full-duplex data communication. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 500 kb/s. The device integrates two drivers and two receivers in a single package. Key electrical specifications include a maximum operating temperature of +85 °C and a minimum of -40 °C. It features an active current consumption of 1 mA and includes a shutdown mode for power conservation. Electrostatic discharge protection is rated at 15 kV.

Feature Summary

• Integrates dual drivers and dual receivers for complete RS-232 signal conversion
• Supports low-power operation with a dedicated shutdown control pin
• Provides robust electrostatic discharge protection for interface reliability

Applications

• Industrial equipment serial communication ports
• Portable battery-powered instrumentation
• Modem and fax machine interfaces

Procurement Notes

Verify the specific suffix IPW confirms the SOIC-20 package and industrial temperature grade during sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates before procurement. Ensure the component matches the exact part number to avoid functional discrepancies related to voltage ranges or packaging types.

Selection Notes

Select this component when dual independent RS-232 channels are required within a compact surface-mount footprint. The 3 V to 5.5 V operating range allows compatibility with both 3.3 V and 5 V logic systems. The 500 kb/s data rate capability suits standard asynchronous communication needs without requiring higher-speed alternatives.

Part Context

This part belongs to the MAX3222 family of multichannel RS-232 line drivers and receivers. The family is characterized by its ability to operate from a single power supply while generating the necessary positive and negative voltages for RS-232 standards using external capacitors.

Replacement Considerations

MAX3222EIDW: Alternative package variant (SOIC-20) with identical electrical characteristics.
