MAX1406EAE+

Drivers, Receivers, Transceivers Overview

The MAX1406EAE+ is a ±15kV ESD-protected, EMC-compliant RS-232 interface IC featuring three transmitters and three receivers. It operates with VCC between +4.5V and +5.5V, VDD between +10.8V and +13.2V, and VSS between -10.8V and -13.2V. The device guarantees data rates up to 230kbps with a typical supply current of 185µA for both IDD and ISS at VCC=5V and VDD/VSS=±12V. It provides enhanced ESD protection rated at ±15kV (Human Body Model), ±8kV (IEC1000-4-2 Contact Discharge), and ±15kV (IEC1000-4-2 Air-Gap Discharge). The component is housed in a 16-pin SSOP package and supports an operating temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'EAE' corresponds to the -40°C to +85°C temperature range and 16-pin SSOP package configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust ESD immunity for RS-232 interfaces without external protection diodes. Ensure power supply sequencing flexibility is required, as the device handles any supply powering up first. Verify that the 16-pin SSOP footprint matches the target PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the Maxim Integrated MAX1406 family of RS-232 transceivers. It shares functional similarities with other devices in the series but is distinguished by its specific ESD protection ratings and guaranteed 230kbps data rate capability. The family includes variants with different packaging options such as DIP and Wide SO.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1406 is pin-compatible with the MC145406. Other MAX1406 variants with different temperature ranges or packages may serve as alternatives if electrical characteristics align with system requirements.

Drivers, Receivers, Transceivers FAQ

Does the MAX1406 require external protection diodes for ESD?

No, the MAX1406 incorporates built-in ±15kV ESD protection structures on all pins, eliminating the need for external protection diodes.

What is the input logic threshold voltage for the receivers?

The receiver inputs have a logic threshold high (VIHT) of 2.0V and a logic threshold low (VILT) of 0.8V.

How does the MAX1406 handle unused transmitter inputs?

Unused transmitter inputs should be tied to GND or VCC to minimize power consumption, as there are no internal pull-up resistors.
