MAX3311EEUB

Overview

The MAX3311EEUB is a low-power, single-channel RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +5V supply and supports data rates up to 460kbps. The device features ±15kV ESD protection on transmitter outputs and receiver inputs using the Human Body Model. It includes a shutdown mode with typical current consumption of 1µA. The unit is housed in a 10-pin µMAX package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated ±15kV ESD protection for robust I/O pin handling
• Ultra-low power shutdown mode reducing supply current to 1µA
• Single charge-pump design requiring only three external capacitors
• Receiver remains active during shutdown state

Applications

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

Procurement Notes

Verify the specific suffix 'EEUB' confirms the extended industrial temperature range (-40°C to +85°C) and the 10-pin µMAX package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ordering specifications match the exact functional requirements for the single-transmitter, single-receiver topology.

Selection Notes

Select this component for applications requiring minimal external capacitance and high ESD tolerance. The MAX3311E variant is appropriate when shutdown functionality is required, unlike the MAX3313E which lacks this feature but includes an INVALID output. Verify that the system power supply can support the transient currents generated by the internal charge pump during operation.

Part Context

This part belongs to the MAX3311E/MAX3313E family of low-power RS-232 transceivers. It shares the same core architecture as the MAX3313E but differs in control features, specifically offering a shutdown pin for power management. Both devices utilize a proprietary low-dropout transmitter output stage to ensure compatibility with standard RS-232 voltage levels from a single +5V source.
