MAX211IDBR

Drivers, Receivers, Transceivers Overview

The MAX211IDBR is a fully integrated RS-232 transceiver manufactured by Texas Instruments, designed for full-duplex data communication. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 120kbps. The device integrates four drivers and five receivers, housed in a 28-pin SSOP package. It features low standby current through an automatic power-down mode and includes ESD protection rated at 15kV on all pins.

Drivers, Receivers, Transceivers Feature Summary

• Integrates charge pump circuitry to generate required RS-232 voltage levels from a single 5V supply
• Includes automatic power-down mode that reduces standby current to less than 30uA when inputs are unconnected
• Provides 15kV electrostatic discharge (ESD) protection on all RS-232 signal I/O pins

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring reliable serial communication
• Portable equipment utilizing battery-powered RS-232 interfaces
• Modems and fax machines needing full-duplex data transmission

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'IDBR' corresponds to the tape-and-reel packaging variant rather than tube packaging. Confirm the operating temperature grade matches industrial requirements (-40°C to +85°C). Ensure the 28-SSOP footprint aligns with the target PCB design constraints before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a full-duplex RS-232 solution with integrated charge pumps is required. It is suitable for applications needing four transmit and five receive channels. Consider alternative pinouts if fewer drivers or receivers are sufficient, as other family members may offer different configurations.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX211/MAX221/TRS213 family of RS-232 transceivers. These devices share similar internal architectures but differ in driver/receiver counts and package options. The IDBR designation specifically indicates the industrial temperature range and reel packaging format used for automated assembly processes.

Drivers, Receivers, Transceivers Replacement Considerations

The TRS213IDBR is a pin-compatible replacement within the same manufacturer portfolio. Verify functional equivalence regarding driver strength and receiver sensitivity before substitution.
