MAX3311EUB+T

Overview

The MAX3311EUB+T 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 with EIA/TIA-232-compatible output levels. The device integrates a single inverting charge pump requiring only three 0.1µF capacitors. Key electrical parameters include a supply voltage range of 4.5V to 5.5V, a typical operating current of 250µA, and a shutdown current of 1µA. It features a propagation delay of 0.15µs and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates a single transmitter and receiver in a compact 10-pin µMAX package
• Features a proprietary low-dropout transmitter output stage for operation from a single +5V supply
• Includes a 1µA low-power shutdown mode that disables the charge pump and transmitter
• Receiver remains active during shutdown mode to detect incoming signals

Applications

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

Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the specific suffix matches the required temperature grade and packaging format. Ensure compliance with RoHS directives as indicated in the product documentation before finalizing procurement orders.

Selection Notes

Select this component when a single full-duplex RS-232 channel is required in space-constrained designs. It is suitable for applications needing low standby power consumption due to its microamp shutdown capability. Verify that the system operates within the specified 4.5V to 5.5V supply range and requires data rates up to 460kbps.

Part Context

This part belongs to the MAX3311/MAX3313 family of low-power RS-232 transceivers. The MAX3311 variant specifically provides a shutdown pin for power management, whereas the MAX3313 includes an INVALID output signal. Both share identical electrical characteristics and pinouts, differing primarily in these functional additions.

Replacement Considerations

Direct substitutes within the same family include the MAX3313EUB+T, which offers an INVALID output instead of shutdown control. Other variants like the MAX3311CUB+T are available for commercial temperature ranges.
