MAX1406CWE

Drivers, Receivers, Transceivers Overview

The MAX1406CWE is a ±15kV ESD-protected, EMC-compliant RS-232 transceiver featuring three transmitters and three receivers. It operates on a +4.5V to +5.5V VCC supply with ±10.8V to ±13.2V for VDD and VSS. The device supports data rates up to 230kbps with a typical propagation delay of 0.4µs. Supply currents are less than 500µA for IDD and ISS, and less than 1mA for ICC. It is housed in a 16-pin Wide SO package and functions within a temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CWE' corresponds to the required commercial temperature range (0°C to +70°C) and the 16-pin Wide SO package format. Confirm that the ordering information matches the exact part number variant needed for your bill of materials, as other suffixes indicate different thermal or packaging specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when EMC compliance and high ESD immunity are critical requirements for RS-232 interfaces. It serves as a drop-in replacement for designs using the MC145406, eliminating the need for external protection components while maintaining compatibility with standard PC communication software protocols.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX1406 family of RS-232 interface ICs designed by Maxim Integrated. The family includes variants such as the MAX1406CPE (DIP) and MAX1406CAE (SSOP), offering flexibility in package selection while maintaining identical electrical characteristics and functional pinouts across the series.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1406 is explicitly stated to be pin and functionally compatible with the MC145406. Designers can substitute existing MC145406 implementations with the MAX1406 to achieve improved ESD performance without altering the board layout or circuit topology.
