MAX1406CAE+

Drivers, Receivers, Transceivers Overview

The MAX1406CAE+ 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, 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 transmitter propagation delay of 4µs and receiver propagation delay of 4µs. Supply currents are typically 185mA for IDD and ISS, and 240mA for ICC at 230kbps. It is housed in a 16-pin SSOP package and functions within an operating temperature range of 0°C to +70°C.

• Flow-through pinout configuration simplifies PCB layout for existing RS-232 designs.

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix CAE corresponds to the 16-pin SSOP package and the C grade indicating a 0°C to +70°C operating temperature range. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust ESD immunity without external protection diodes. Ensure supply voltages remain within specified limits (+4.5V to +5.5V for VCC) and that the application demands full-duplex communication with three independent channels. Verify thermal dissipation requirements for the SSOP package under maximum load conditions.

Drivers, Receivers, Transceivers Part Context

This part belongs to the Maxim Integrated MAX1406 family of RS-232 interface ICs. It serves as a drop-in replacement for legacy MC145406 designs while offering superior electromagnetic compatibility and static discharge resilience. The CAE suffix specifically denotes the small-outline plastic package variant suitable for space-constrained applications.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1406CAE+ is pin-compatible with the MC145406. Other variants in the MAX1406 series include MAX1406CPE (DIP) and MAX1406CWE (Wide SO). Cross-referencing with MAX1406EAE is possible if extended temperature ranges (-40°C to +85°C) are required.

Drivers, Receivers, Transceivers FAQ

Does the MAX1406 require external ESD protection components?

No, the device incorporates internal structures providing ±15kV HBM and ±8kV IEC contact discharge protection, eliminating the need for external diodes.

What is the guaranteed data rate for the MAX1406?

The device is guaranteed to operate at data rates up to 230kbps with a worst-case load of 3kW and 1000pF.

How does the MAX1406 handle power-up sequencing?

The device is not sensitive to power-supply sequencing; any of the three supplies (VCC, VDD, VSS) can power up first without requiring external protection.
