MAX3314EKA+T

Overview

The MAX3314EKA+T is an RS-232-compatible transceiver operating from external ±5V supplies. 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 ±3.7V output levels. A shutdown function reduces supply current to 1µA while keeping the receiver active. It is housed in an 8-pin SOT23 package and operates within a temperature range of -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 under specified loads
• Supports data transmission rates up to 460kbps
• Compact 8-pin SOT23 surface-mount package

Applications

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

Procurement Notes

Verify the component matches the specific E-series temperature rating (-40°C to +85°C) and the K suffix for the SOT23 package. Confirm the trailing '+T' indicates tape-and-reel packaging if required by assembly equipment. Ensure the source documentation explicitly identifies this part as manufactured by Analog Devices Inc./Maxim Integrated to validate authenticity.

Selection Notes

Select this component when designing systems requiring minimal power consumption during idle periods without disabling serial reception. It is suitable for applications needing reliable RS-232 communication at moderate speeds with strict space constraints due to its small footprint. Verify that the system can provide stable external ±5V rails, as internal charge pumps are not included.

Part Context

This part belongs to the MAX3314 family of low-power RS-232 transceivers. The 'E' designation specifies the extended industrial temperature range, distinguishing it from the commercial 'C' variant. The 'K' indicates the 8-pin SOT23 physical package, while 'UA' would denote µMAX and 'SA' would denote SO packages within the same electrical specification set.

Replacement Considerations

Direct functional substitutes include other parts from the MAX3314 series such as the MAX3314EUA or MAX3314ESA, which share identical electrical characteristics but differ only in package type. Cross-brand replacements require verification of pin compatibility and voltage level standards.
