MAX211IDBRG4

Drivers, Receivers, Transceivers Overview

The MAX211IDBRG4 is a single-channel RS-232 transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 250 kbps. The device features low supply current, typically 6 mA during transmission and 1.8 mA during reception. It includes integrated charge pumps that eliminate the need for external capacitors, supporting both +5 V and ±12 V RS-232 levels. The component is housed in an 8-pin SOIC package and functions reliably across an industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry removes the requirement for external flying capacitors
• Single-supply operation compatible with standard +5 V logic systems
• Full compliance with EIA/TIA-232-F and ITU-T V.28 standards
• Low power consumption design suitable for battery-operated applications

Drivers, Receivers, Transceivers Applications

• Portable computers and notebook PCs requiring serial communication interfaces
• Modems and fax machines utilizing RS-232 signaling
• Industrial control systems needing robust serial data transmission
• Point-of-sale (POS) terminals and barcode scanners

Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the G4 suffix to confirm lead-free status and RoHS compliance. Confirm the package variant matches the required PCB footprint. Ensure the operating environment stays within the specified -40°C to +85°C range. Check for any specific tape-and-reel or cut-tape packaging requirements from the distributor. Validate that the supply voltage remains stable between 3.0 V and 5.5 V during operation.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-driver, single-receiver RS-232 solution is needed without external capacitor support. Compare against the MAX211E variant if extended fault protection or higher input thresholds are required. Consider the OPA2172IDRG4 only if operational amplifier functionality is needed instead of serial interface capabilities. Evaluate the LMV321IDBVRG4 if low-voltage analog signal processing is the primary design goal rather than digital serial communication.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX211 family of RS-232 transceivers designed for low-power, single-supply applications. It serves as a direct replacement for older multi-capacitor RS-232 solutions. The G4 suffix indicates a green, lead-free package compliant with international environmental standards. It is distinct from dual-transceiver models like the MAX3221EIPWRG4 which offer additional channels.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX211IDBR is the non-green equivalent. The MAX211EIDBR offers enhanced fault protection. The TRS213IDBR provides four drivers and five receivers for more complex interfaces.
