MAX3311EEUB+T

Overview

The MAX3311EEUB+T is a low-power, single RS-232 transceiver designed for +5V operation. It features ±15kV Human Body Model ESD protection on all I/O pins and supports data rates up to 460kbps. The device utilizes a proprietary low-dropout transmitter output stage and a single inverting charge pump requiring only three 0.1µF capacitors. In shutdown mode, the supply current drops to 1µA while the receiver remains active. It operates within a temperature range of -40°C to +85°C and is housed in a 10-pin µMAX package.

Feature Summary

• Integrated ±15kV ESD protection on transmitter outputs and receiver inputs
• Ultra-low power consumption with 1µA shutdown mode
• Single charge-pump design requiring minimal external components
• Receiver remains functional during shutdown state

Applications

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

Procurement Notes

Verify that the ordering suffix 'E' confirms the extended industrial temperature range (-40°C to +85°C). Confirm the '+T' designation indicates tape-and-reel packaging. Ensure the component matches the specific Maxim Integrated datasheet specifications before integration into the bill of materials.

Selection Notes

Select this component when a single-channel RS-232 interface is required with robust ESD tolerance. It is suitable for applications needing low standby power without sacrificing receiver availability. Compare against the MAX3313E if an INVALID signal output is necessary to detect cable presence.

Part Context

This part belongs to the MAX3311E/MAX3313E family of low-power RS-232 transceivers. It shares the same core architecture as the commercial grade MAX3311ECUB but offers an extended operating temperature range. The device simplifies PCB layout by minimizing the number of required external capacitors.

Replacement Considerations

The MAX3311ECUB serves as the commercial-grade equivalent with a 0°C to +70°C range. The MAX3313EEUB provides identical electrical performance but includes an INVALID output pin for cable detection.
