MAX213CWI+

Drivers, Receivers, Transceivers Overview

The MAX213CWI+ is a +5V-powered RS-232 transceiver from the Analog Devices/MAXIM family, designed for single-supply operation. It integrates four drivers and five receivers within a 28-pin Wide SO package. The device operates at data rates exceeding 120kbps while maintaining ±5V output levels compliant with EIA/TIA-232E specifications. It utilizes an internal charge pump to generate required voltage swings without external bipolar supplies. The component functions within a supply voltage range of 4.5V to 5.5V and supports an industrial temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the need for external bipolar power supplies
• Maintains EIA/TIA-232E signal levels at high data rates under standard loading conditions
• Includes two receiver channels that remain active during low-power shutdown mode
• Features TTL/CMOS compatible inputs with on-chip pullup resistors for unused driver inputs

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CW' corresponds to the Wide SO package and commercial temperature range when sourcing replacements. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ordering details match the exact pinout and electrical characteristics defined in the current datasheet revision.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring four transmit and five receive channels in a compact form factor. The integrated charge pump simplifies design by removing external voltage conversion components. Consider the shutdown functionality for power-sensitive designs where ring indicator monitoring is necessary during low-power states.
