MAX3314CSA+

Overview

The MAX3314CSA+ is a single-channel RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates with external ±5V power supplies and supports data rates up to 460kbps. The device features a low-power shutdown mode that reduces supply current to 1µA while keeping the receiver active. It utilizes an 8-pin SO package and includes a flow-through architecture for simplified PCB layout.

Feature Summary

• Low-power shutdown capability with active receiver
• RS-232-compatible signal levels
• Flow-through pin configuration

Applications

• Digital Cameras
• PDA
• GPS
• POS
• Telecommunications
• Handy Terminals
• Set-Top Boxes

Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature range. The CSA suffix indicates an 8-pin SO package with a commercial operating temperature range of 0°C to +70°C. Confirm RoHS compliance status based on the plus sign in the part number.

Selection Notes

Select this component when a single-channel RS-232 interface is required with minimal power consumption. Ensure the system provides separate positive and negative voltage rails, as internal charge pumps are not included. Verify that the load capacitance does not exceed 1000pF for guaranteed performance at maximum data rates.

Part Context

This device belongs to the MAX3314 family of RS-232 transceivers designed for portable applications. It offers a compact solution for serial communication interfaces where space and power efficiency are critical constraints. The family includes variants with different packages and extended temperature ranges.

Replacement Considerations

Compatible alternatives within the same product line include the MAX3314EUA (µMAX package) and MAX3314EKA (SOT23 package). These parts share identical electrical characteristics but differ in physical footprint and thermal properties.
