MAX3221IDBE4

Overview

The MAX3221IDBE4 is a single transmitter and receiver RS-232 line transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 250Kbps. The device features full-duplex communication with single-ended signal types for both drivers and receivers. It utilizes a 16-pin SSOP package (0.209 inch width) suitable for surface-mount installation. The component complies with EIA/TIA-232-F, RS-232, and V.28 interface standards. It functions in point-to-point topologies and includes three-state driving modes. The operational temperature range spans from -40°C to +85°C.

Feature Summary

• Integrates a single driver and receiver for full-duplex RS-232 communication
• Operates on a single 3V to 5.5V power supply without external charge pumps
• Provides robust ESD protection capabilities for reliable operation
• Supports standard RS-232 protocols including EIA/TIA-232-F and V.28

Applications

• Point-to-point serial communication links
• Industrial control systems requiring RS-232 interfaces
• Embedded devices needing single-channel serial data transmission

Procurement Notes

Verify the specific suffix 'E4' against official Texas Instruments documentation to confirm RoHS compliance status and manufacturing origin. Confirm that the 16-SSOP package dimensions match the design footprint requirements. Check current part status as LTB to assess long-term availability for production planning.

Selection Notes

Select this component when a single-channel RS-232 transceiver is required for low-power applications. Ensure the system voltage falls within the 3V to 5.5V range. Verify that the 250Kbps data rate meets the application's speed requirements. Confirm compatibility with the 16-SSOP package for PCB layout constraints.

Part Context

This part belongs to the MAX3221 family of single RS-232 transceivers. It shares core functionality with variants like MAX3221IDBR but differs in packaging and compliance suffixes. The IDBE4 designation indicates industrial temperature range and specific environmental compliance attributes defined by the manufacturer.

Replacement Considerations

MAX3221IDBR serves as a functional equivalent with identical electrical specifications. TRSF3221EIDBR offers similar performance with potential pinout or feature variations requiring verification. Always consult official datasheets before substituting to ensure package and parameter compatibility.
