MAX213CDBR

Drivers, Receivers, Transceivers Overview

The MAX213CDBR is a Texas Instruments RS-232 interface integrated circuit featuring four drivers and five receivers. It operates on a single 4.5 V to 5.5 V supply with a typical current consumption of 20 mA. The device supports full-duplex communication at data rates up to 120 kb/s. It includes an internal shutdown mode for power reduction and provides ±15 kV electrostatic discharge (ESD) protection on all RS-232 lines. The component is housed in a 28-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuit eliminates the need for external dual-voltage supplies.
• Robust ±15 kV ESD protection ensures reliability across all RS-232 signal lines.
• Shutdown feature significantly reduces power consumption during idle periods.
• Single 5 V supply operation simplifies system design and power requirements.

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring reliable serial communication.
• Modem interfaces and telecommunications equipment.
• Point-of-sale (POS) terminals and payment systems.
• Medical instrumentation with serial data transfer needs.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CDBR' against the manufacturer's latest documentation to confirm package type, temperature grade, and tape-and-reel packaging specifications. Ensure compatibility with existing PCB footprints for the 28-pin SOIC format. Check for end-of-life status or alternative recommendations from Texas Instruments before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring multiple RS-232 channels with high ESD tolerance. It is suitable for applications needing low standby power via shutdown mode. Compare driver/receiver counts against other family members if fewer channels are sufficient. Verify that the 120 kb/s speed meets the application's timing requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX213 series of multichannel RS-232 transceivers. It shares functional similarities with the MAX211 and MAX208 but offers a specific combination of four drivers and five receivers. The CDBR suffix indicates a commercial temperature range and reel packaging, distinguishing it from tube-packaged variants like the IDB.

Drivers, Receivers, Transceivers Replacement Considerations

The TRS213 is a pin-compatible replacement offering similar functionality. Other options include the MAX211 for reduced channel counts or the MAX3243 for lower power consumption and wider voltage support. Verify electrical parameters and package dimensions before substitution.
