MAX211IDB

Drivers, Receivers, Transceivers Overview

The MAX211IDB is a low-power RS-232 transceiver manufactured by Texas Instruments, housed in a 28-pin SSOP package. It integrates four drivers and five receivers to support full-duplex communication with a data rate of 120 kb/s. The device operates on a single 4.5 V to 5.5 V supply and draws only 300 µA in shutdown mode. It includes internal charge pumps that eliminate the need for external capacitors, requiring only two 0.1 µF capacitors for operation. The component provides ESD protection of ±15 kV on RS-232 lines and meets all requirements of the TIA/EIA-232-F standard.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual charge pumps to generate required voltage levels without external components
• Provides robust electrostatic discharge protection on signal lines
• Features a dedicated shutdown mode to minimize power consumption during idle periods

Drivers, Receivers, Transceivers Applications

• Portable equipment requiring serial communication interfaces
• Modems and fax machines
• Industrial control systems with RS-232 connectivity

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DB' confirms the 28-lead SSOP package variant. Confirm RoHS compliance status as manufacturing processes evolve. Check for obsolescence notices since this component belongs to an older generation of interface ICs. Ensure the source document matches the exact part number to avoid confusion with similar MAX21x series devices.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require a compact solution for RS-232 communication without external charge pump capacitors. It is suitable for battery-powered applications due to its low quiescent current and shutdown capability. Compare against newer TRS213 variants if surface-mount tape-and-reel packaging is preferred over tubes.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX213 family of low-power RS-232 transceivers. It shares architectural similarities with the MAX211 but may differ in pinout or specific electrical characteristics compared to other members like the MAX232. It represents a transition toward integrated solutions that reduce board space by eliminating bulky external capacitors typically needed for voltage inversion.

Drivers, Receivers, Transceivers Replacement Considerations

The TRS213IDBR is a documented equivalent within the same functional family. Verify pin compatibility before substitution. Other alternatives include the MAX232IDR for through-hole designs or newer low-voltage variants if system power rails have changed.
