MAX3311EUB+

Overview

The MAX3311EUB+ is a low-power, +5V EIA/TIA-232-compatible transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates one transmitter and one receiver within a 10-pin µMAX package. The device operates from a single +5V supply with a voltage range of 4.5V to 5.5V. It supports data rates up to 460kbps while maintaining RS-232-compatible output levels. Key electrical parameters include a typical operating supply current of 250µA and a shutdown supply current of 1µA. The component features a proprietary low-dropout transmitter output stage and requires only three 0.1µF capacitors for operation.

Feature Summary

• Features a 1µA low-power shutdown mode that disables the charge pump and transmitter output.
• Includes a receiver that remains active during shutdown mode for continuous signal monitoring.
• Utilizes a single inverting charge pump requiring only three external capacitors.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm RoHS compliance status through manufacturer datasheets or authorized distributors. Ensure the component matches the required industrial specifications before integration into final designs.

Selection Notes

Select this component for applications requiring minimal power consumption and compact footprint. The 10-pin µMAX package is suitable for space-constrained portable devices. Verify that the system operates within the specified +5V supply range and meets the thermal requirements for the extended temperature grade.

Part Context

This part belongs to the MAX3311/MAX3313 family of RS-232 transceivers. The MAX3311 variant specifically provides a shutdown feature, whereas the MAX3313 includes an INVALID output signal. Both share identical pinouts and core functionality but differ in specific control outputs.

Replacement Considerations

Direct substitutes within the same series include the MAX3311CUB for commercial temperature ranges. Cross-family replacements require verification of pin compatibility and electrical characteristics against the original design requirements.
