MAX3313EEUB+T

Overview

The MAX3313EEUB+T is a low-power, single RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +5V supply and supports data rates up to 460kbps with ±3.7V output levels. The device integrates a single inverting charge pump requiring only three 0.1µF capacitors. It features ±15kV ESD protection on I/O pins per the Human Body Model. An INVALID output signals active cable connection. Operating temperature range is -40°C to +85°C. Supply current is typically 250µA at +5V.

Feature Summary

• Integrated INVALID output detects active RS-232 cable connections
• Robust ±15kV ESD protection on transmitter outputs and receiver inputs
• Single charge-pump design requires only three external capacitors
• Maintains RS-232-compatible voltage levels at high data rates

Applications

• Digital Cameras
• GPS Receivers
• Point-of-Sale (POS) Terminals
• Telecommunications Equipment
• Set-Top Boxes

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and package integrity upon receipt. Ensure storage conditions meet specified humidity sensitivity levels. Cross-reference ordering suffixes with official documentation to validate temperature ranges and packaging types before finalizing procurement orders.

Selection Notes

Select this model when an INVALID signal is required to detect peripheral connectivity. The MAX3311E variant lacks this feature but includes a shutdown mode. Verify that the application environment stays within the -40°C to +85°C operating range. Ensure the power supply remains stable at +5V to maintain proper charge pump operation and signal integrity during transmission.

Part Context

This component belongs to the MAX3311E/MAX3313E family of low-power RS-232 transceivers. It shares the same physical footprint and electrical interface as the MAX3311E, differing primarily in functional outputs. The EEUB suffix denotes the extended industrial temperature range (-40°C to +85°C) and the 10-pin µMAX package configuration.

Replacement Considerations

The MAX3311EEUB+T serves as a functional substitute if the INVALID pin is unnecessary. Both devices share identical pinouts and electrical characteristics except for the specific output functionality. Verify that the replacement part meets the same environmental and voltage requirements.
