MAX211CWI

Drivers, Receivers, Transceivers Overview

The MAX211CWI+ is a +5V-powered RS-232 transceiver featuring four drivers and five receivers. It operates within a 4.5V to 5.5V supply range, drawing 11mA to 20mA in active mode and reducing to 1µA in shutdown. The device supports data rates up to 120kbps with a typical propagation delay of 10µs. It utilizes an integrated charge pump requiring only four 0.1µF external capacitors. The component is housed in a 28-pin Wide SO package and functions reliably across a commercial temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual charge-pump circuitry for single-supply operation without bipolar voltage requirements
• Includes low-power shutdown mode that disables charge pumps and transmitter outputs to minimize current consumption
• Features enable control pins to place receiver outputs into high-impedance states for bus multiplexing

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring extended operational life
• Handheld devices with limited board space constraints
• Portable diagnostic equipment utilizing serial communication interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature grade (0°C to +70°C) rather than the industrial grade ('E'). Confirm the 'W' suffix corresponds to the Wide SOIC package variant. Ensure the '+' suffix denotes compliance with current environmental standards. Cross-reference the manufacturer's official ordering guide to validate availability and exact pinout compatibility before integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring multiple transmit and receive channels on a single +5V rail. The wide SOIC package offers a larger footprint compared to SSOP variants, which may simplify manual assembly or rework processes. Consider the 120kbps maximum data rate limitation against system timing requirements. Evaluate the need for the specific shutdown and enable control logic provided by this model versus simpler alternatives.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX200-MAX209/MAX211/MAX213 family of RS-232 transceivers manufactured by Analog Devices Inc./Maxim Integrated. The MAX211 specifically provides a higher channel count with four drivers and five receivers, distinguishing it from lower-channel models like the MAX202. It shares the same core architecture and capacitor requirements as other members of this series.
