Overview
The MAX3490EEPA+ is a +3.3V-powered, full-duplex transceiver for RS-485 and RS-422 communications. It contains one driver and one receiver operating from a single supply voltage ranging from 3.0V to 3.6V. The device supports data rates up to 12Mbps with guaranteed performance across the industrial temperature range of -40°C to +85°C. It features ±15kV ESD protection on all I/O pins using Human Body Model and IEC standards. The package is an 8-pin Plastic DIP.
Feature Summary
- Full-duplex communication capability with independent transmit and receive channels
- Robust electrostatic discharge protection rated at ±15kV via Human Body Model and IEC 1000-4-2 standards
- Operates directly from a single +3.3V supply without requiring charge pumps
- Interoperable with +5V logic levels
Applications
- Telecommunications systems
- Industrial-control local area networks
- Integrated Services Digital Networks (ISDN)
- Packet switching applications
Procurement Notes
Verify the specific suffix EEPA corresponds to the 8-pin Plastic DIP package and the -40°C to +85°C extended temperature range. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before procurement.
Selection Notes
Select this component when full-duplex operation is required for RS-485 or RS-422 interfaces. It is suitable for environments demanding high ESD immunity and direct +3.3V power supply integration. Ensure the application does not require slew-rate limiting, as this variant operates at full speed.
Part Context
This part belongs to the MAX3483E family of low-power transceivers manufactured by Analog Devices Inc./Maxim Integrated. The family includes half-duplex variants like the MAX3485E and slew-rate-limited versions such as the MAX3483E. The MAX3490E specifically provides full-duplex functionality within this ecosystem.
Replacement Considerations
The MAX3490ESA+ serves as a pin-compatible alternative in an SOIC package. Other family members like the MAX3485E offer similar electrical characteristics but are restricted to half-duplex communication.
