MAX1480ACPI+

Drivers, Receivers, Transceivers Overview

The MAX1480ACPI+ is a complete, electrically isolated RS-485/RS-422 data-communications interface solution housed in a 28-pin wide plastic DIP package. It integrates transceivers, optocouplers, and a transformer to provide isolation between the logic side and the signal path. The device operates on a single +5V supply and supports half-duplex communication with a maximum data rate of 2.5Mbps. It typically withstands 1600V RMS for one minute or 2000V RMS for one second. The operating temperature range is specified from 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates transceivers, optocouplers, and a transformer within a standard DIP package for complete electrical isolation.
• Features short-circuit current limiting and thermal shutdown circuitry to protect driver outputs.
• Includes a fail-safe receiver input that guarantees a known output state when the input is open circuit.

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 component against official Analog Devices documentation to confirm pinout compatibility and isolation ratings. Ensure the specific ordering suffix matches the required temperature range and package style. Cross-reference the datasheet specifications with system requirements before integration.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring high-speed half-duplex communication up to 2.5Mbps. The non-limited slew rate distinguishes it from lower-speed variants. Confirm that the 28-pin DIP footprint fits the target PCB layout and that the isolation voltage meets the safety standards of the application environment.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX1480A/B/C family of isolated interface solutions. It shares architectural similarities with the MAX1490 series but differs in duplex capability. The 'C' suffix indicates the commercial temperature grade, while the 'E' suffix denotes an extended industrial range.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1480AEPI+ serves as a direct replacement offering the same electrical characteristics but with an extended operating temperature range of -40°C to +85°C. Other family members like the MAX1480B offer reduced slew rates for lower data rates.
