MAX3314ESA+

Overview

The MAX3314ESA+ is an RS-232-compatible transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-pin SO package. It operates with dual external power supplies of +5V (VCC) and -5V (V-), each within a range of ±4.75V to ±5.25V. The device features one transmitter and one receiver in a flow-through architecture, supporting data rates up to 460kbps under worst-case loads of 3kΩ and 1000pF. It guarantees minimum RS-232-compatible output levels of ±3.7V. A shutdown function reduces supply current to 1µA while keeping the receiver active. Operating temperature ranges from -40°C to +85°C.

Feature Summary

• Low-power shutdown mode reduces supply current to 1µA while maintaining receiver activity
• RS-232-compatible signal levels with guaranteed ±3.7V output voltage at high data rates
• Flow-through architecture providing independent transmitter and receiver paths

Applications

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

Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm that the ordering suffix matches the specific package type and temperature range requirements for your design. Ensure compliance with RoHS standards as indicated in the product documentation before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring low-power RS-232 communication with external dual power supplies. Consider the 8-pin SO package constraints and verify that the application supports the required ±5V supply rails. Evaluate the 460kbps data rate limit against system timing requirements and ensure adequate decoupling capacitors are included in the design.

Part Context

The MAX3314ESA+ belongs to the MAX3314 series of RS-232 transceivers designed for portable and battery-powered applications. It offers a compact solution for serial communication interfaces where power consumption is critical. The device integrates standard RS-232 functionality into a small footprint, making it suitable for space-constrained electronic designs requiring reliable serial data transmission.

Replacement Considerations

Compatible alternatives include the MAX3314CSA+, MAX3314EUA+, and MAX3314EKA+. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement part meets the same temperature range and package requirements as the original design specification.
