MAX3311CUB

Overview

The MAX3311CUB is a low-power, +5V EIA/TIA-232-compatible transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features one transmitter and one receiver in a 10-pin µMAX package. The device operates from a single +5V supply using a proprietary low-dropout output stage and a single inverting charge pump requiring only three 0.1µF capacitors. It supports data rates up to 460kbps with RS-232-compatible output levels. The MAX3311 includes a 1µA shutdown mode that disables the charge pump and transmitter while keeping the receiver active. Operating temperature range is 0°C to +70°C.

Feature Summary

• Single Transceiver Configuration
• Low-Power Shutdown Mode
• RS-232-Compatible Operation

Applications

• Digital Cameras
• PDAs
• GPS
• POS
• Telecommunications

Procurement Notes

Verify the specific ordering suffix 'CUB' corresponds to the commercial temperature range (0°C to +70°C) and the 10-pin µMAX package format. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before procurement. Ensure the component source is an authorized channel to guarantee authenticity and traceability for industrial applications.

Selection Notes

Select the MAX3311CUB when a single full-duplex RS-232 channel is required in a compact surface-mount package. This part is suitable for designs needing low standby current via shutdown mode while maintaining receiver activity. Choose this over the MAX3313 if the INVALID cable detection feature is not needed. Ensure the application environment stays within the 0°C to +70°C operating range.

Part Context

The MAX3311CUB belongs to the MAX3311/MAX3313 family of low-power RS-232 transceivers. It shares the same core architecture as the MAX3311EUB but differs in the specified operating temperature range. The 'C' suffix denotes the commercial grade, while 'E' denotes extended grade. Both variants utilize the same 10-pin µMAX footprint and electrical interface specifications.

Replacement Considerations

The MAX3311EUB is a direct functional substitute with an extended temperature range (-40°C to +85°C). Verify thermal requirements before swapping. Other Maxim RS-232 transceivers may require different capacitor configurations or pinouts.
