Overview
The MAX3223EIDBG4 is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates from a single 3-V to 5.5-V supply and includes on-chip charge pumps for generating the required voltages. The device features two drivers and two receivers, supporting data rates up to 500 kb/s. It provides ±15-kV IEC ESD protection on the RS-232 lines. The component is housed in a 20-pin SSOP package and is rated for operation over an extended temperature range of -40°C to +85°C.
Feature Summary
- Integrated charge pump eliminates external voltage generation requirements
- Robust electrostatic discharge protection compliant with IEC standards
- Supports full-duplex communication with independent driver and receiver channels
Applications
- Industrial control systems requiring reliable serial communication
- Portable instrumentation and battery-powered devices
- Modem and peripheral interface connections
Procurement Notes
Verify the specific suffix G4 indicates lead-free composition and RoHS compliance when sourcing. Confirm the SSOP-20 package dimensions match your PCB footprint constraints. Ensure the operating voltage range aligns with your system's power supply rails before integration.
Selection Notes
Select this component when high ESD immunity is critical for RS-232 interfaces. Compare against standard MAX3223 variants if lower cost is prioritized over enhanced protection. Verify that the 500 kb/s data rate meets your application's throughput requirements compared to slower legacy transceivers.
Part Context
This part belongs to the MAX3223 family of multichannel RS-232 transceivers. It shares functional similarities with the MAX3223EIDBR but differs in packaging and specific environmental ratings. The E-suffix typically denotes enhanced ESD protection capabilities compared to non-E variants within the same series.
Replacement Considerations
The MAX3223EIDBR is a pin-compatible alternative within the same family. The TRS3223EIDB offers similar functionality with potential minor parameter variations. Verify package compatibility and electrical specifications before substituting.
