MAX3314EUA+T

Overview

The MAX3314EUA+T is an RS-232-compatible transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates with external +5V and -5V power supplies, consuming 30µA during active operation and reducing to 1µA in shutdown mode. The device features a single transmitter and receiver within an 8-pin µMAX package. It supports data rates up to 460kbps while maintaining minimum ±3.7V output levels under worst-case loads of 3kΩ and 1000pF. The receiver remains active during shutdown, and the unit functions across a temperature range of -40°C to +85°C.

Feature Summary

• Low-power shutdown capability reduces supply current to 1µA while keeping the receiver active
• RS-232-compatible performance with guaranteed ±3.7V output levels at high data rates
• Flow-through architecture supporting full-duplex communication

Applications

• Digital Cameras
• Personal Digital Assistants (PDA)
• GPS Systems
• Point-of-Sale (POS) Terminals
• Telecommunications Equipment

Procurement Notes

Verify that the ordering suffix 'T' indicates tape-and-reel packaging rather than tube delivery. Confirm the 'E' designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure the '+T' suffix aligns with lead-free RoHS compliance requirements for your specific manufacturing process.

Selection Notes

Select this component when designing systems requiring low standby power without disabling the receive path. It is suitable for applications needing reliable RS-232 signaling at 460kbps with minimal external components. Consider the 8-pin µMAX package constraints regarding thermal dissipation and board space availability compared to larger SO packages.

Part Context

This part belongs to the MAX3314 family of RS-232 transceivers designed for portable electronics. It shares functional similarities with other Maxim low-voltage interface ICs but is specifically optimized for dual-supply ±5V operation. The family includes variants like the MAX3314CKA and MAX3314ESA differing primarily in package type and temperature rating.

Replacement Considerations

Direct substitutes include MAX3314CUA and MAX3314CSA, which share identical electrical specifications but differ in operating temperature ranges and physical packages.
