MAX3222EIDGSR

Overview

The MAX3222EIDGSR is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic systems. The device features two drivers and two receivers, enabling full-duplex communication with a data rate capability of 500 kb/s. It incorporates a shutdown mode that reduces power consumption to approximately 1 µA. The component provides 15 kV electrostatic discharge (ESD) protection on the RS-232 lines and is housed in a DGSR package variant of the SOIC form factor. It is rated for operation over an extended temperature range from -40°C to +85°C.

Feature Summary

• Integrated dual-channel RS-232 transceiver functionality for bidirectional serial communication
• Low-power shutdown mode designed to minimize energy consumption during idle periods
• Robust ESD protection rated at 15 kV to safeguard against electrostatic discharge events

Applications

• Industrial control systems requiring reliable serial communication interfaces
• Portable equipment utilizing battery power where low standby current is critical
• Modems and fax machines implementing standard RS-232 protocols

Procurement Notes

Verify the specific suffix 'DGSR' indicates tape-and-reel packaging when sourcing components. Confirm the 'E' grade designation aligns with required performance specifications for industrial environments. Ensure compatibility with existing PCB footprints for the DGSR package type before procurement.

Selection Notes

Select this component for applications requiring dual-channel RS-232 connectivity with low quiescent current. The 3 V to 5.5 V operating range ensures compatibility with various logic families. Consider the 500 kb/s data rate limit when designing high-speed serial links. Verify thermal requirements for the intended operating temperature range.

Part Context

This part belongs to the MAX3222 family of multichannel RS-232 transceivers. The 'E' suffix typically denotes an extended temperature range version suitable for industrial applications. The 'DGSR' suffix specifies the surface-mount package and reel packaging configuration, distinguishing it from tube-packaged variants like the IDW.

Replacement Considerations

Direct pin-to-pin replacements within the same family include the MAX3222EIDR or MAX3222EIDW. Verify that substitute parts maintain the same DGSR package dimensions and electrical characteristics. Cross-reference datasheets to ensure equivalent ESD protection levels and shutdown current specifications.
