MAX211CAI

Drivers, Receivers, Transceivers Overview

The MAX211CAI is a +5V-powered RS-232 transceiver featuring four drivers and five receivers. It utilizes integrated charge pump circuitry to generate ±10V from a single supply, eliminating the need for external bipolar voltage sources. The device supports data rates exceeding 120kbps while maintaining EIA/TIA-232E compliance. It operates within a temperature range of 0°C to +70°C and is housed in a 28-pin wide small-outline (SO) package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump eliminates requirement for external bipolar power supplies
• Low-power shutdown mode reduces supply current to typical 1µA
• TTL/CMOS compatible inputs with internal pullup resistors on unused drivers

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring extended operation
• Handheld devices with limited board space
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the 'C' suffix indicates the commercial temperature range of 0°C to +70°C. Confirm the 'AI' suffix corresponds to the 28-pin wide SO package. Ensure the component meets RoHS standards if required by the specific manufacturing process.

Drivers, Receivers, Transceivers Selection Notes

Select this model when four transmit channels and five receive channels are necessary. The integrated charge pump simplifies design by removing external capacitors from the main signal path. Verify that the operating environment remains within the commercial temperature limits specified for the CAI variant.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX200–MAX209/MAX211/MAX213 family of +5V RS-232 transceivers. The MAX211 specifically provides higher channel density compared to standard dual-driver variants, making it suitable for complex serial communication interfaces.

Drivers, Receivers, Transceivers Replacement Considerations

MAX211EWI+ offers identical electrical performance but covers an extended industrial temperature range (-40°C to +85°C). Both parts share the same pinout and functional specifications.
