MAX1490AEPG

Drivers, Receivers, Transceivers Overview

The MAX1490AEPG is a complete, electrically isolated RS-485/RS-422 data-communications interface solution in a hybrid microcircuit. It supports full-duplex communication with a maximum data rate of 2.5Mbps and operates on a single +5V supply. The device features short-circuit current limiting and thermal shutdown protection. It typically withstands 1600V RMS (1 minute) or 2000VRMS (1 second) isolation voltage. The receiver input includes a fail-safe feature that guarantees a known output if the input is open circuit. It is housed in a 24-pin DIP package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated electrical isolation using transceivers, optocouplers, and a transformer within a standard DIP package.
• Supports full-duplex communication with high-speed data transmission capabilities up to 2.5Mbps.
• Includes driver short-circuit current limiting and thermal shutdown circuitry for enhanced reliability.
• Receiver input provides fail-safe functionality to ensure a known logic state during open-circuit conditions.

Drivers, Receivers, Transceivers Applications

• Isolated RS-485/RS-422 Data Interface
• Transceivers for EMI-Sensitive Applications
• Industrial-Control Local Area Networks
• Automatic Test Equipment
• HVAC/Building Control Networks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'EPG' against the manufacturer's official documentation to confirm temperature range and compliance status. Ensure the component matches the required 24-pin DIP package dimensions. Confirm that the logic side power requirements align with the single +5V supply specification provided in the datasheet.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is required alongside galvanic isolation between logic and signal grounds. It is suitable for applications needing high data rates up to 2.5Mbps without slew-rate limiting. Consider alternative models like the MAX1490B if reduced EMI via slew-rate limiting is prioritized over maximum speed.

Drivers, Receivers, Transceivers Part Context

The MAX1490AEPG belongs to the MAX1480A/MAX1480B/MAX1480C/MAX1490A/MAX1490B family of isolated RS-485/RS-422 interfaces. This family integrates transceivers, optocouplers, and transformers into a single hybrid microcircuit. The MAX1490 variants specifically support full-duplex operation, distinguishing them from the half-duplex MAX1480 series.
