MAX213CDB

Drivers, Receivers, Transceivers Overview

The MAX213CDB is a multi-channel RS-232 line driver and receiver manufactured by Texas Instruments, designed for 5V power supplies. It integrates four drivers and five receivers within a single SSOP-28 package to support full-duplex communication at data rates up to 120 kb/s. The device operates with a supply voltage range of 4.5 V to 5.5 V and draws approximately 20 mA of quiescent current. It features integrated shutdown functionality and provides ±15 kV electrostatic discharge (ESD) protection on all RS-232 lines. The component supports operation across an industrial temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates four independent drivers and five receivers in a compact surface-mount package
• Provides robust ±15 kV ESD protection on all RS-232 signal lines
• Includes dedicated shutdown pin for significant power reduction during idle periods

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring multiple serial ports
• Computer peripheral interfaces and modem connections
• Point-of-sale terminals and barcode scanners

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CDB' against the manufacturer's official documentation to confirm the SSOP-28 package variant and commercial temperature grade. Confirm RoHS compliance status through the latest datasheet revision. Check for end-of-life notices or obsolescence warnings, as older RS-232 transceivers may have limited production availability. Ensure the supplier provides traceable origin documents for quality assurance purposes.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require four transmit and five receive channels without external charge pumps. Compare against the MAX213CDW for SOIC-28 packaging alternatives if board space allows wider traces. Consider the MAX3243 series if lower operating currents or extended voltage ranges are required for battery-powered applications.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX213 family of multichannel RS-232 transceivers. It serves as a direct functional replacement for legacy parts like the TRS213. The device simplifies PCB layout by eliminating the need for external capacitors typically required in earlier generations of RS-232 drivers.

Drivers, Receivers, Transceivers Replacement Considerations

The TRS213IDB is a verified equivalent part number offering identical electrical specifications and pinout compatibility within the same SSOP-28 package.
