MAX3314EEUA+

Overview

The MAX3314EEUA+ is a single RS-232 transceiver from the MAX3314E family, designed for ±5V operation. It features one transmitter and one receiver in a flow-through architecture, supporting data rates up to 460kbps with loads of 3kΩ and 1000pF. The device guarantees minimum RS-232-compatible output levels of ±3.7V. It incorporates robust ESD protection rated at ±15kV (Human Body Model), ±8kV (IEC Contact Discharge), and ±15kV (IEC Air-Gap Discharge). Supply current is 30µA during operation and reduces to 1µA in shutdown mode, where the receiver remains active. It is housed in an 8-pin µMAX package.

Feature Summary

• Integrated ±15kV ESD protection on RS-232 I/O pins compliant with IEC standards
• Low-power shutdown mode reducing supply current to 1µA while keeping the receiver active
• Guaranteed high-speed performance up to 460kbps under worst-case loading conditions
• Low-dropout transmitter stage ensuring ±3.7V compatible output levels

Applications

• Digital Cameras
• PDAs
• GPS Systems
• POS Terminals
• Telecommunications Equipment

Procurement Notes

Verify the specific suffix EEUA against official documentation to confirm the extended temperature range (-40°C to +85°C) and the 8-pin µMAX package type. Ensure that external power supplies providing both positive and negative voltages are correctly decoupled with capacitors as specified in the typical operating circuit diagrams.

Selection Notes

Select this component when a single-channel RS-232 interface is required with high ESD immunity and low standby power consumption. It is suitable for applications needing full-duplex communication without the complexity of multiple drivers or receivers. Confirm that the system can provide separate positive and negative voltage rails for proper operation.

Part Context

The MAX3314EEUA+ belongs to the MAX3314E series of RS-232 transceivers manufactured by Analog Devices/Maxim Integrated. This family provides a compact solution for serial communication interfaces, offering various package options including SOT23, SO, and µMAX to accommodate different board space constraints.

Replacement Considerations

Direct replacements within the same family include MAX3314ECUA (commercial temperature range) and MAX3314EESA (SOIC package). Verify pin compatibility and thermal specifications before substituting.
