MAX211CDWG4

Drivers, Receivers, Transceivers Overview

The MAX211CDWG4 is a fully integrated, low-power CMOS transceiver designed for RS-232 communication. It includes on-board charge pumps that generate the required positive and negative supply voltages from a single 5V source, eliminating the need for external components. The device features two drivers and two receivers, supporting data rates up to 120 kbps. It operates within a temperature range of -40°C to +85°C and is housed in an 16-pin TSSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the requirement for external capacitors or dual power supplies.
• Provides full RS-232 compliance with EIA/TIA-232-F standards for reliable signal transmission.
• Features fail-safe receiver design to ensure a high logic output state during open-circuit conditions.

Drivers, Receivers, Transceivers Applications

• Portable battery-powered equipment requiring minimal component count
• Industrial control systems with single-supply constraints
• Modem interfaces and serial communication ports

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free (Pb-free) packaging compliant with RoHS directives. Confirm the 'CDW' designation corresponds to the commercial temperature grade (-40°C to +85°C) and the 16-pin TSSOP physical footprint. Ensure compatibility with existing board space and thermal management requirements for this package type.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single 5V supply is available and external charge pump capacitors must be avoided to save PCB area. Compare against the MAX211CPE for through-hole applications or the MAX211EIG4 for extended industrial temperature ranges. Verify that the 120 kbps speed meets the system's throughput requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX211 family of RS-232 transceivers. It serves as a direct replacement for older discrete solutions or dual-supply transceivers. The 'G4' suffix denotes Green/RoHS-compliant manufacturing, while 'CDW' specifies the commercial temperature range and TSSOP package variant within the broader MAXIM Integrated portfolio.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes include the MAX211CPE (DIP package), MAX211EIDG4 (extended temp, TSSOP), and MAX211EPE (extended temp, DIP). Cross-reference electrical specifications such as drive voltage and current consumption to ensure functional equivalence in the target application.
