MAX211CWI+

Drivers, Receivers, Transceivers Overview

The MAX211CWI+ is a full RS-232 transceiver featuring four drivers and five receivers, designed for single +5V supply operation. It integrates dual charge-pump circuitry requiring only four 0.1µF external capacitors to generate ±10V internal rails. The device supports data rates up to 120kbps with driver output slew rates reaching 30V/µs. Operating within a commercial temperature range of 0°C to +70°C, it includes shutdown and enable control pins to minimize power consumption. The component is housed in a 28-pin Wide SO package.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual charge-pump voltage converters to eliminate the need for bipolar ±12V supplies
• Provides TTL and CMOS compatible inputs with guaranteed receiver thresholds exceeding EIA/TIA-232E specifications
• Includes shutdown and enable control functions to reduce supply current and manage bus states

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment
• Handheld devices
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'C' confirms the commercial operating temperature range of 0°C to +70°C. Confirm the 'W' indicates the 28-pin Wide Small-Outline package. Ensure the '+' suffix denotes compliance with current environmental directives. Cross-reference the manufacturer's official part numbering guide to validate that these suffixes do not alter the electrical function or pinout configuration.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a full duplex interface with multiple transmit and receive lines is required on a single +5V rail. The integrated charge pump simplifies design by reducing external capacitor count compared to older generations. Verify that the 120kbps maximum data rate meets system requirements. Consider the shutdown feature if power conservation during idle periods is necessary for the application.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX200-MAX209/MAX211/MAX213 family of +5V RS-232 transceivers. It shares architectural similarities with the MAX213 but lacks the specialized ring indicator monitoring capabilities active during shutdown found in the MAX213 variant. The MAX211 provides a balanced solution for general-purpose serial communication interfaces requiring robust noise immunity and low component count.
