MAX3314CSA

Overview

The MAX3314CSA is a single RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-SOIC package. It supports data rates up to 460 kbps and operates with a supply voltage range of 4.75 V to 5.25 V. The device features full-duplex communication with one driver and one receiver. Key electrical specifications include a maximum operating current of 30 µA and ESD protection rated at 15 kV. It is designed for serial communication applications requiring low power consumption and robust signal integrity within standard RS-232 voltage levels.

Feature Summary

• Integrated ESD protection rated at 15 kV for enhanced reliability
• Low power operation with 30 µA maximum supply current
• Supports data transmission speeds up to 460 kbps
• Single channel full-duplex RS-232 transceiver functionality

Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems utilizing RS-232 communication protocols
• Modems and portable instruments needing robust ESD protection

Procurement Notes

Verify the specific suffix 'CSA' against official Analog Devices documentation to confirm temperature grade and packaging details. Ensure compatibility with existing PCB footprints for the 8-SOIC package. Cross-reference the manufacturer's latest datasheet for any recent pinout or electrical characteristic updates before finalizing procurement plans.

Selection Notes

Select this component when a single-channel RS-232 interface is required with minimal power consumption. The 460 kbps speed limit suits most standard asynchronous serial communications. Consider the 15 kV ESD rating for environments prone to electrostatic discharge. Verify that the 5V supply voltage aligns with the system's power architecture.

Part Context

The MAX3314 belongs to the Maxim Integrated MAX331 family of RS-232 transceivers. This series is characterized by its ability to operate from a single 5V supply while providing compliant RS-232 output voltages. The CSA variant specifically denotes the commercial temperature range and SOIC-8 surface-mount package configuration within the broader product line.

Replacement Considerations

Check the official Analog Devices replacement guide for direct pin-to-pin compatible alternatives. Verify if upgraded versions within the MAX3232 or MAX3243 families meet the specific 460 kbps and 30 µA current requirements. Confirm package compatibility for the 8-SOIC form factor.
