MAX3222CDBRG4

Overview

The MAX3222CDBRG4 is a fully compliant RS-232 transceiver manufactured by Texas Instruments, designed for low-power applications. It integrates two drivers and two receivers within a single package, supporting data rates up to 250 kbps. The device operates from a single power supply ranging from 3 V to 5.5 V and draws only 1 mA of supply current during active operation. It features ESD protection exceeding ±15 kV according to the Human Body Model. The component is housed in a 20-pin SSOP package with a width of 5.30 mm and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrates dual drivers and dual receivers for complete RS-232 communication functionality
• Supports low-power operation with 1 mA active supply current draw
• Provides robust electrostatic discharge protection on all pins

Applications

• Portable equipment requiring RS-232 connectivity
• Modems and fax machines
• PDA systems and handheld terminals
• Industrial control panels with serial interfaces

Procurement Notes

Verify the specific suffix G4 indicates lead-free status and RoHS compliance when sourcing. Confirm the package type matches the design requirements as variations exist across the MAX3222 family. Check manufacturer documentation for any recent product change notices or lifecycle status updates before finalizing procurement plans.

Selection Notes

Select this component for designs requiring full duplex RS-232 communication with minimal power consumption. Ensure the system voltage falls within the 3 V to 5.5 V range. Consider the 20-pin SSOP footprint constraints during PCB layout. Verify that the 250 kbps data rate meets the application's speed requirements compared to higher-speed alternatives.

Part Context

This part belongs to the MAX3222 series of RS-232 transceivers from Texas Instruments. It shares functional similarities with other members like the MAX3222CDBR but includes specific manufacturing and compliance suffixes. The series is known for using small external capacitors, reducing overall board space requirements for portable devices.

Replacement Considerations

The MAX3222EIDBR is listed as a manufacturer-recommended alternative. Verify pin compatibility and electrical specifications before substitution. Other variants in the MAX3222 family may offer different temperature ranges or packaging options.
