MAX1406CWE+T

Drivers, Receivers, Transceivers Overview

The MAX1406CWE+T is a ±15kV ESD-protected, EMC-compliant RS-232 transceiver featuring three transmitters and three receivers. It operates with VCC between +4.5V and +5.5V, and dual supplies VDD (+10.8V to +13.2V) and VSS (-10.8V to -13.2V). The device guarantees data rates up to 230kbps with propagation delays of 4µs max. Supply currents are typically 185µA for IDD and ISS, and 240µA for ICC at 230kbps. It functions within a commercial temperature range of 0°C to +70°C and utilizes a 16-pin Wide SO package.

Drivers, Receivers, Transceivers Feature Summary

• Enhanced electrostatic discharge protection rated at ±15kV Human Body Model and ±15kV IEC1000-4-2 Air-Gap Discharge.
• Pin and functionally compatible with the industry-standard MC145406 for direct design upgrades.
• Flow-through pinout architecture supporting full-duplex communication without requiring external shutdown control.

Drivers, Receivers, Transceivers Applications

• Telecommunications equipment
• Modems
• Printers
• Instruments meeting IEC1000-4-2 standards

Drivers, Receivers, Transceivers Procurement Notes

Verify the suffix 'W' corresponds to the 16-pin Wide SOIC package and '+T' indicates tape-and-reel packaging. Confirm RoHS compliance status through official documentation. Ensure the operating environment remains within the specified 0°C to +70°C commercial temperature range for this specific grade.

Drivers, Receivers, Transceivers Selection Notes

Select this component when upgrading existing MC145406 designs to meet stringent European EMC requirements without changing the PCB layout. It is suitable for applications requiring guaranteed 230kbps performance with minimal supply current consumption. Verify that the system can provide the required ±12V auxiliary rails for optimal operation.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX1406 family of RS-232 interface ICs designed for high ESD immunity. The 'C' designation specifies the commercial temperature range, while 'W' identifies the wide small-outline package. Analog Devices / Maxim Integrated manufactures this series to facilitate robust serial communication in noisy industrial environments.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1406 is pin-compatible with the MC145406. Other variants in the MAX1406 family include MAX1406CPE (DIP) and MAX1406EWE (Extended Temperature Wide SO), which share identical functionality but differ in package type or operating temperature range.
