MAX3311CUB+T

Overview

The MAX3311CUB+T is a single-channel RS-232 transceiver in a 10-pin µMAX package. It operates from a +5V supply with data rates up to 460kbps, utilizing a single charge pump and three 0.1µF capacitors. The device features a low-power shutdown mode drawing 1µA, where the transmitter disables but the receiver remains active. Operating temperature range is 0°C to +70°C.

Feature Summary

• Single transceiver configuration (1Tx/1Rx) in a compact 10-pin µMAX package
• Low-power shutdown mode reducing supply current to 1µA while keeping the receiver active
• RS-232-compatible operation enabled by a proprietary low-dropout output stage

Applications

• Digital Cameras
• PDAs
• GPS Systems
• POS Terminals
• Telecommunications Equipment

Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm the C suffix indicates commercial temperature range (0°C to +70°C). Ensure ordering documentation matches the exact MAX3311CUB+T designation to avoid confusion with the industrial grade E variant.

Selection Notes

Select this part for applications requiring minimal external components and low standby power. The MAX3311 is suitable when the receiver must remain active during system sleep states. Verify that the +5V logic interface aligns with the host system requirements before implementation.

Part Context

This component belongs to the MAX3311/MAX3313 family of low-power RS-232 transceivers. While the MAX3313 includes an INVALID output signal, the MAX3311 omits this feature. Both share identical electrical characteristics and pinouts except for the INVALID pin function.

Replacement Considerations

The MAX3311EUB+T serves as the industrial temperature range equivalent. Direct functional replacements include other single-channel RS-232 transceivers with similar shutdown capabilities and µMAX packaging constraints.
